Numb3rs

Season 2

Judgment Call

Bettor or Worse

1. Sinclair (Alimi Ballard) imitates a Jamaican delivery guy to gain access to a potential suspect's home. The actor previously starred in Dark Angel playing Herbal Thought, a Jamaican bike delivery guy.
2. The car they are looking for is a 2001 Saturn Ion, but the Ion didn't come out until 2003. Also the key fob was not a GM brand fob.

Obsession

1. Larry's "new" car is a 1931 Ford Model A Deluxe Roadster.
2. Navi Rawat and Samaire Armstrong both starred on The O.C. (2003).

Calculated Risk

Assassin

Soft Target

1. John Heard (the head Homeland Security agent) played a character with the same first name as his character here (Peter) in both Home Alone and Home Alone 2.

Convergence

1. When Charlie is speaking to Larry Fleinhart (roughly eight minutes into the episode) about his relationship with Marshall Penfield, he walks by a chalkboard with a number of equations written on it. Several of these can be clearly seen 8 minutes and 21 seconds into the episode. The lowermost equation, unlike the others, appears to have been included as a joke, as it reads: 1+1=2. Everything else on the chalkboard involves notational formalism related to more complicated mathematics, and this simple arithmetic equation is clearly unrelated.
2. Colin Hanks and Diane Farr previously starred in the tv show "Roswell." Diane Farr played the mother of Colin Hanks's character's friend.

In Plain Sight

1. The cast and relevant crew members had to sign waivers that they wouldn't reveal exactly how the magic trick was done. The trick revealed on the show is slightly different from the actual trick.
2. The MATH in this episode included: Flock behavior, steganography and matrices - error correction code.
3. Colby's license plate on his black Ford is: (California) 2GEE645.

Toxin

1. The plant shown in the last scene is *not* a pot plant but a Schefflera or Umbrella Tree.
2. At the end of this episode, Allen Charlie Don and Larry are having a discussion in the living room area and it appears to be a pot plant over Alan's right shoulder.

Bones of Contention

1. Jane Carr and Judd Hirsch both starred in the TV show "Dear John."
2. Graham Greene and Rob Morrow were in the series Northern Exposure together.

Scorched

The OG

1. Tamara Taylor, who plays community center director Olivia Rawlings in this episode, went on to play Dr. Camille Saroyan in Bones; in that show she is head of the Forensic Division of the Jeffersonian and often works closely with the FBI to solve crimes. Aldis Hodge, who plays suspected shot caller Travis, went on to play Alec Hardison in Leverage; in that show he is a thief/hacker who, along with a team that includes a former FBI agent, works outside the law (usually) to solve crimes and right wrongs.

Double Down

1. While doing a facial recognition check, David Sinclair says he is using "The Huntington Tech online Facebook" to search for the identities of the High Rollers. This Episode aired January of 2006. Facebook did not open it's membership to the general public until September of 2006. At the time of this episode, Facebook was still for college students

Harvest

1. David Krumholtz played a psychotic young man in an episode of ER in which he attacked people because he thought that someone wanted to take his internal organs. In this episode, Larry recounts a recurring dream of someone wanting to take his internal organs, and at the end, Charlie is reluctant to sign a donor card because he wants to "hang on to his internal organs." Lots of "internal organs" references.
2. Charlie's birthday, according to his driver's license, is September 5, 1975.

The Running Man

1. In the final scene, it is really Rob Morrow playing the piano.
2. In the first scene, a runner is wearing a red "Mathematica" T-shirt. Mathematica is a computer product from Wolfram Research, widely used in the mathematical and scientific community for programming, computation, and visualization. The design on the shirt shows a type of recursive, fractal figure.

Protest

1. The book "Essays on Revolution" on the episode was shown at the end of the episode and the cover says that the book was written by Cheryl Heuton and Nicolas Falacci, the two creators of the show.
2. Judd Hirsch's character, Alan Eppes, is revealed to have a history of protesting the Vietnam war, for which the FBI have a case file on him. Hirsch's character in Running on Empty (1988) had a similar history: in that film, his character Arthur Pope and his wife Annie, who also have two sons, are fugitives wanted by the FBI for a Vietnam War protest bombing. That film was based on the 1970 bombing of Sterling hall at the University of Wisconsin; is this episode, the character Matt Stirling is a suspected bomber and fugitive.

Mind Games

1. The opening song is Praise by Sevendust

All's Fair

Dark Matter

Guns and Roses

1. Lesley Fera (ATF Agent Wilson) and Eric Steinberg (ATF Agent Rho) would both later star in Pretty Little Liars (2010) as Veronica Hastings & Colonel Wayne Fields, respectively.

Rampage

1. Charlie and Don discuss how spaghetti can't be broken into exactly two pieces. A decade after the episode two MIT researchers discovered that twisting the noodle nearly 360 degrees before bending it results in a two-piece break. They believe this discovery may have far-reaching impact into other sorts of fracturing problems.

Backscatter

Undercurrents

1. The edition of the I Ching ("Book of Changes") that Dr. Fleinhardt consults is volume 19 in the Bollingen Series, a line of books on Asian religion and philosophy published by Princeton University Press. It was translated from the original Chinese into German by Richard Wilhelm and rendered into English by Cory Baynes; the foreword was written by Dr. Carl Jung. This is considered one of the most authoritative versions of the I Ching in English, although it is not the most popular one due to the fact that it is a straight translation and not a collection of pat answers.
2. The I Ching is a Chinese oracle that uses hexagrams, figures composed of six lines of four types. They can be broken (-- --) or unbroken (-----), and each of those types can be fixed or changing. The lines are generated by random processes, with the traditional method using yarrow sticks and a more modern "quickie" method of tossing three coins. The result is one of sixty-four hexagrams which are interpreted according to the text accompanying each figure in the Book of Changes.
3. The 64 hexagrams of the I Ching can be interpreted numerically in at least two different ways. First by the numbers assigned to the diagrams in the Book of Changes from 1 to 64 and second as a series of binary numbers ranging from 0-63. The binary interpretation can, in turn, be interpreted in two different ways depending on which type of line is interpreted as a 0 or a 1.

Hot Shot

1. JoBeth Williams makes a guest appearance in this episode as Margaret Eppes, Alan's late wife (and mother of Don and Charlie). Williams previously starred with Judd Hirsch in Teachers (1984).
