Sara is seen carrying a large piece of bamboo though the lab. This seems to be a running joke among production. Large, unmanageable props are usually carried through the lab by either Sara or Catherine.

Greg: Ninety-nine bottles of beer on the wall, ninety-nine bottles of beer. Swab one down, run it through CODIS, ninety-eight bottles of beer on the wall.
Nick: (Walking in) Whatever happened to "take on down and pass it around"? That was the best part.
Greg: You know us lab rats have to do something to get through the day.

Editing goof: This episode opens and closes in a movie theatre. At the beginning of the episode one of the couples seen from behind is Gil and Catherine. They do not go to see a movie till the end of the episode.

Episode Plot

The plot of this episode is patterened after the Alfred Hitchcock movie Strangers on a Train.

Catherine: Mr. Siskel, Mr. Ebert, may I have a casue of death, please?

Catherine is referring to Siskel and Ebert, two movie reviewers of the 1980s.

Other movies mentioned in this episode include The Dirty Dozen and Guns of Navaronne.

Gil: This is the last art house left in Vegas. I saw Baraka here, on a double bill with Koyaanisquatsi.
Catherine: Was there anyone else here?
Gil: Sure.
Catherine: With you?
Gil: No.

This is a repeat of the joke from "Pledging Mr. Johnson" regarding the calamari restaurant.

Catherine: Whoo! Theatres are like nightclubs; they should always keep the lights off.

Greg makes a similar reference regarding nightclubs in "Viva Las Vegas".
