The Naked Truth

1. When zooming in on the top of New York Magazine to the heading; Honeywell & Cootes, the next title down is Mystery vs. History: is it better not to know?, a reference to a later episode.
2. When zooming in on the top of New York Magazine to the heading, after title Mystery vs History, there is a reference to a past episode with Marshall's joke "Willem... Dafoe".
3. The Google search Marshall does has many call backs to series in-jokes including pages on him having been the largest baby born in his home county until a recent 18 lb baby was born, Bask-ICE-ball, his Vanilla Fudge nickname, being a resident of the "Dowistrepla" neighborhood, a post on a Bigfoot message board, and his all lawyer funk band, "The Funk, The Whole Funk, And Nothing But The Funk".

5. The song playing in the background while Ted was meeting the different girls at the newsstand was "Victoria" by The Kinks. This is foreshadowing the fact that Ted runs into Victoria at the end of the episode where the song plays again.
6. You can see when Marshall finds the first video of him streaking as "Beercules" that there are images beside the videoplayer that is from the second time Marshall is streaking. As of the time they are watching this video the other streaking would not have happened yet.

Ducky Tie

1. The Narrator (future Ted) doesn't make any comments on the events of the episode until the very last scene.
2. In the scene where Ted took Victoria to the bus, you can see that the license plates from the bus are from California not from New York.
3. In the flashback where Ted first talks to Victoria at the ball, 'Lenny Kravitz' is in the background, holding the silver ladle and points to his forehead as if he's been hit by it. This reveals that Robin was telling the truth when she said Ted freaked out when he first sees Victoria.

6. All of the daily specials in the diner, shown at the beginning of the episode with Robin and Kevin, feature turkey.

4. The credits in Barney's presentation show that it was directed by McG.
5. First episode to feature the "No boogey boarding allowed" outside the bar. This comes up later in "Disaster Averted"

Noretta

1. When Barney and Nora are about to walk out onto Barney's balcony, we get a glimpse of the front of his apartment. There is no 'giant TV', but instead, there is a fireplace.
2. Lily has a "midnight snack" in bed in this episode where as she was opposed to eating in bed in the previous season to avoid ants.

The Slutty Pumpkin Returns

1. When Robin informs Barney that he is one fourth Canadian he responds by saying, "No! That's not true. That's impossible!" Which is the same response verbatim Luke Skywalker has when told by Darth Vader that he is his father in "Star Wars".
2. There are 128 episodes between the original Slutty Pumpkin episode and this one.
3. This episode features two songs parodied by 'Weird Al' Yankovic, who appeared in the previous episode How I Met Your Mother: Noretta (2011). Barenaked Ladies' 'One Week' became Yankovic's 'Jerry Springer' and James Brown's 'Living in America' is parodied as 'Living with a Hernia'.
4. At the end when Barney is fighting the Canadian version of himself, the body double, who's used to play the other version of himself when both are in one shot, has much darker hair than Barney does.
5. In 'The Slutty Pumpkin Returns' Lily tries to convince Marshall to move into her grandparents house by offering to buy him a pinball machine. When he asks where he will position it in the house she replies "You can stick it anywhere you want". This is an in-joke on her Buffy co-star Sarah Michelle Gellar who used the same line under very different circumstances in her film Cruel Intentions (1999).
6. Last episode in which Barney appears without a suit.
7. The song "One Week" by the Barenaked Ladies is featured in this episode and Katie Holmes' character dances to it jokingly, but in a sexual manner. The same song and similar gimmick is used at the end of American Pie, where Alyson Hannigan had a supporting role.
8. Barney says "Classic Shmosby" when Ted admits he told the Slutty Pumpkin that he loved her. A call back to a line often said by Punchy, Ted's best friend from Cleveland.
9. The final scene where the American Barney is battling the Canadian Barney, it is a reference to Superman III where Clark Kent battles Superman in the junk yard. The same sound and special effects from that scene are used.

Disaster Averted

1. In the cold open, when Barney is beckoned into the alley by a man in a fez, behind them is a sign reading "DUK TAI TRADING COMPANY," an obvious reference to his duck tie, the disappearance of which the scene is meant to explain.
2. The opening Barney action sequence contains a couple of nods to Indiana Jones: the man wearing the fez in the alley and the rescuing of the young boy referred to by Barney as "the kid".
3. In the cutaway scene with Lily and Marshall in the bathtub, Lily is reading a book titled "Pamela Was Robbed." This is likely referencing director Pamela Fryman's loss in the Outstanding Directing category at the Prime Time Emmy Awards (for the episode "Subway Wars").
4. In this episode, Barney claims that he is older and taller than Ted. Ted denies that Barney is taller, but agrees that he's older. In real life, Neil Patrick Harris is a year older than Josh Radnor, and the two men are the same height.
5. In the scene where Marshall is going through his Edgar Allen Poe phase, there is a raven figurine on the shelf behind him. This is a clear node to Edgar Allen Poe's "The Raven".
6. Lily is the only group member who doesn't have any siblings. Ted has a sister, Marshall has 2 brothers, Robin has a sister, and Barney has a half-brother on his mother's side, plus a half-brother and half-sister on his father's side. Lily does however have at least one female cousin, a nun who we met at her bridal shower.
7. In the opening sequence, the roof Barney ascends is the same roof where he and Marshall previous conducted their "conference calls" when the two were co-workers at Goliath National Bank.
8. Barney threatens to take off his tie saying, "I'm going to like the way I look, I guarantee it.". This is a reference to the television commercials for Men's Warehouse, in which the company owner proclaims "you're gonna like the way you look, I guarantee it.". Appropriately Men's Warehouse a store that is known for selling chiefly men's suits,
9. In season 7's "Disaster Averted", when talking about how you haven't lived until someone puts a sign up for something you did, they flash a sign saying "no motorcycles on the casino floor." Later in the season Barney steals a motorcycle in a casino while trying to get Marshall out of Atlantic City, telling us the sign was for him.
10. In season 7 episode 9, New York was hit by a hurricane, Robin and Ted suggested Marshall about naming his baby Hurricane Erikson. Later in Episode 11, Ted and Barney decide to adopt a baby, they name it Hurricane-Stinson-Mosby/Hurricane-Mosby-Stinson.
11. One year after this episode aired Hurricane Sandy hit the New York area

Tick Tick Tick

1. With the exception of Barney and Robin, all other main characters in this episode (Ted, Marshall, Lily, Nora, Kevin) wear purple.
2. While Ted, Marshall, and Lily, are sitting at the concert, the people behind them are eating sandwiches like Ted and Marshall were. Of course eating sandwiches is code of smoking pot.
3. David Neher and Jerry Minor both have small roles in this episode. Both of whom also have recurring roles in Community (2009).

The Rebound Girl

1. Much of the episode is centered around Ted and Barney becoming a couple to raise a child together. Neil Patrick Harris and Josh Radnor actually played a couple in the play "The Paris Letter".
2. During the scene where Robin went with Lily and Marshall to their suburban house in Long Island, you can see a white dog sculpture near the entrance door, this is a nod to a FRIENDS episode where there was a white dog sculpture at Joey's home when he moved out of his and Chandler's apartment

Symphony of Illumination

1. Scott takes out a sandwich and begins to eat it. As in previous episodes, it can be inferred that he is actually smoking marijuana., since that is a running gag.
2. Robin states she would not go to Cleveland even for $125 Million dollars paid over six years. Referring to Lebron James leaving the Cleveland Cavaliers to join the Miami Heat. Ted responds with "where's that ring he promised everyone?" Lebron James would go on to beat the Oklahoma City Thunder that year for his first NBA Finals Championship.
3. Sole appearances of Andra Nechita and Noah Schnacky as Robin and Barney's fictional children.
4. Barney's old friend, "Insane Duane", gets a girl pregnant because of a one-night-stand. This is the same way Barney becomes a daddy in the final episode.
5. The opening and for much of the program features narration by Robin to her children, presumably a product of her future marriage to Barney. Near the end, it is revealed they were figments of her imagination, and Ted finishes the narration.

Tailgate

1. The website for Puzzles Bar, shown in this episode, is real. You can access it at puzzlesthebar.com.
2. Second and last time the apartment's piano is played. The first time was in How I Met Your Mother: Slapsgiving (2007).
3. In the flashback scene where Marshall learns that "more is merrier" the young Marshall is wearing a purple jacket that is supposed to be a Minnesota Vikings jacket but says Kamloops [British Columbia] on the back and has a patch on the sleeve that says Chilliwack [British Columbia].
4. The Puzzles theme song is very similar to the Cheers theme song.
5. Ted plays the piano for the Puzzles song. In the final season he tells Barney and Robin that he will take piano lessons and perform at their wedding dressed as Liberace as a wedding present for them.

46 Minutes

1. During the poker game, one of the Russians is eating Oreos out of a poker chip tray. This is a reference to John Malkovich's Russian poker playing character, Teddy KGB, who eats Oreos the same way in Rounders (1998).
2. This is the shows 150th episode.

The Burning Beekeeper

1. Barney refers to himself as 'Special Agent Gary Powers' when talking to Geraldine. Gary Powers was actually a CIA agent who was shot down while flying over Soviet airspace in 1960
2. The piano music heard between the scenes in the living room, dining room and kitchen is "Flight of the Bumblebee" by Nikolai Rimsky-Korsakov.
3. Mickey says there are 10,000 bees in the basement. In using this number he is accurately citing the approximate number of bees that are contained in a starter colony called a "nuc" (short for nuclear hive). This small box contains just 4 frames as compared to a permanent box hive which most commonly holds 5, 8, or 10 frames, with 8 and 10 frames being most common. A typical established colony contains between 20,000-80,000 bees depending on many factors including such things as maturity, time of year, health, availability of food, and size and number of boxes comprising the modular "Langstroh-type" hive.
4. Despite being from Canada, a country known for being extremely polite, in the episode, Robin is accused by both Ted and Marshall of being someone who yells at strangers unprovoked.
5. Ted quotes SunTzu, saying "Never give up, never surrender. " This is actually a quote from the movie Galaxy Quest, which is what he tells Robin after she says the quote to him earlier, as seen later in the episode.
6. The song that Lilly plays a while into the episode, which also is playing when Mr. Coots runs through the house on fire in a beekeeper suit is titled Burnin' For You, performed by Blue Oyster Cult.

The Drunk Train

1. This episode marks Alyson Hannigan's 148th appearance as Lily Aldrin, exceeding her 147 episodes as Willow on Buffy/Angel.
2. First credited appearance of Becki Newton who plays Quinn.
3. Ted is revealed to be a Taurus while Barney is a Scorpio.
4. Ted says he once knew a girl whose favorite band is Glee. Glee was written by Ian Brennan. Ian Brennan went to Prospect High School in Mount Prospect, Illinois with Jennifer Morrison(Zoey).
5. In the flash forward scene, the wall in Marshall and Lilly's bedroom is blue instead of yellow as has been shown in their room in their new house. This is a clue that they move into Ted's old apartment before the baby is born.

No Pressure

1. In series 7 episode 17 No Pressure, at approximately 11.06 you can see Conan O'Brien in the background of Mclarens Pub as Barney runs off to find Marshall and Lilys' sex tape
2. During the flashback in the car ride to Ted and Stella's wedding Barney is doing the dance to Beyonce's "Single Ladies" in the back seat.
3. On season 7 episode 17 on the opening scene shows a movie theater and on the movies playing it shows "The Wedding Bride III" which is also mentioned in Season 9 episode 19.
4. When the camera cuts to Ted and Robin's apartment after Barney finds the sex tape, onscreen reads "46 minutes later", which is exactly how much time it takes to get from Marshall and Lily's place in Long Island to Ted and Robin's place. We found this out in Episode 14, called "46 Minutes".
5. "When a door closes...well, you know the rest" is derived from "When God closes a door, He opens a window"
6. Conan O'Brien: by the bar entrance when Barney leaps out of the booth and heads for the door.
7. At the beginning of "No Pressure", Ted tells his kids that he has not said "I love you" to a woman since he said it to Robin after she broke up with Kevin. While he did date Victoria for a little while after this, he never does say "I love you" onscreen, even after he proposes. So, assuming he didn't say it at some point off screen, he is telling the truth.
8. The film that Ted and Tracey want to see is The Wedding Bride 3

Karma

1. When Robin is reading what is Lily's journal entry about Marshall's Mum in the book Lily gave her, the camera clearly shows the page she is reading from and it is empty
2. Arielle Reitsma who plays Kismet, started her career as an extra in films such as Bride Wars (2009), and Surrogates (2009).

The Broath

1. At 14:56, when the entire gang is taking the 'Broath', Ted tells Marshall not to touch his face, you can hear off camera one of the crew laugh. The show is not shot in front of a live audience due to it's quick scene changes and flashbacks, so it would have to have been someone on set.
2. The college drummers Ted scolds are modeled after Ted, Marshall, and Lily's younger selves.
3. Ned, Martin, And Millie eating sandwich is a reference to the shows ongoing gag to a sandwich being marijuana
4. Marshall states in this episode he hit his growth spurt in 10th grade. In Season 6 episode 2 "House Cleaning" he says he hit 6'4" in the 5th grade and stopped growing

Trilogy Time

1. In the 2006 flash forward, Robin/Rhiannon comes out and speaks French, saying she's French. However, she uses the wrong form of "French." She says, "français," which is only proper if she were a man. She should have said the feminine form, "française," which has a different pronunciation.
2. In the imaginary 2003 Ted imagines there is a sandwhich on the coffee table. A reference to marijuana that had been used throughout the series.
3. The episode, which takes place in 2012, depicts the gang pondering what will happen every three years when they watch the original Star Wars trilogy, with the last future clip depicting them screening the films in 2012. In October of 2012, after the events take place, Disney acquired Lucasfilm and announced that a new Star Wars trilogy was in the works, with Episode VII being ready for release in 2015, which was eventually realized with Star Wars: The Force Awakens.
4. When Marshall enters the apartment in the imaginary version of 2006 he is wearing a medal identical to the ones received by Luke Skywalker and Han Solo in Star Wars: Episode IV - A New Hope (1977) and Chewbacca in Star Wars: The Rise Of Skywalker (2019); Star Wars being a big part of this episode.
5. For the entirety of the 2015 flashforward, Barney's left ring finger is hidden.
6. In the trilogy viewing in 2015, Ted is wearing a wedding ring. However at the end of the series we learn he and Tracy were not actually married until 2019.
7. In the episode Trilogy Time, Ted has a wedding ring on when he is holding his newborn daughter. This conflicts the Last Forever wedding timeline as being 7 years later after both children were born.

Now We're Even

1. The photo shown of Robin on Letterman is not photoshopped - this is from Cobie Smulders' actual appearance on the show in 2011.
2. At the end of this episode, Ted walks into the bar in a green dress and a pregnant Lily and Barney hugging. This is the explained story that Ted couldn't remember from season 6, episode 11, The Mermaid Theory.
3. In 'Now We're Even' Lily has a sex dream featuring Papa Smurf. Neil Patrick Harris starred in The Smurfs (2011) movie alongside 'How I Met Your Mother' guest star Katy Perry.
4. Barney misuses the word "epiphany" in this episode. In Episode 8 of Season 1, The Duel, he uses the word correctly.

Good Crazy

2. The scene at the end of the episode that shows Marshall smoking is in reference to Season 5 Episode 11 "last cigarette ever" when future Ted tells his kids that Marshall smoked his last cigarette the day his son was born.
3. Towards the end of the episode, Ted sees Robin on a beer label. This label reads "Wharmpess Gold" which is a beer created by Randy Wharmpess (Will Forte) who worked with Marshall and Barney at GNB until Marshall fired him in the episode "Canning Randy" (S6E7) to allow Randy to create his own brewery.
4. The disguise Barney wears before kidnapping Marshall slightly resembles that of Stefano from A series of unfortunate events (2017)
5. In earlier episodes, Barney uses the words "algorithm" and "logarithm", both correctly, showing that the writers of the show and Barney's character know what both words mean and how to use them correctly. However, in this episode, when Barney describes to Ted how he instructed the computer to find girls for Ted, he tells Ted he used his "own personal logarithm", which is incorrect. The word he should've used is "algorithm".
6. Ted's 2nd date has fake tattoo sleeves and hides the ends under the leather bracelets her skint one above the write is different to everywhere else.
7. The fake profile Barney made shows multiple hints that it was Barney (such as: "I am a pretty girl who has a master degree in nerdy stuff"
8. In addition to mentioning Ted by name not once, but twice, the online profile has very specific reference to Ted's life such as "I don't mind if he has baggage, like if he was once left at the altar or beaten up by a goat.".
