Henry: You hear that Hodges' is finally looking for his own apartment? Cut the old apron strings.
Catherine: His mother finally kicked him out? Good for her. (edit) Grissom: I bet you five bucks, Greg, that his brain is not as green as his heart.
Doc Robbins: Keep your money in your pockets, Greg. There's a higher vascular nature to the heart and lungs, only the blood vessels of the brain are gonna be green. It's a sucker bet, and you know it.
Greg: Thanks, Doc. (edit) Catherine: 'Atomic Dave's painless removals.' Some kind of pest control gizmo.
Warrick: Apparentally it works. I don't think the squirrels would agree that it's painless though. (edit) Catherine: Looks like Caddyshack out here. Invasion of the ground squirrels.
Warrick (taking a photo of a dead squirrel): Yeah, I got a few casualities out here. (edit) Officer (about his girlfriend taking his pepper spray): But she dances nights at the Acid Strip.
Nick (chuckles): What does she clip the can to her g-string?
Brass: That'd be a detourant to stuffing a tip in there, wouldn't it? (edit)

Grissom: String theory is 'the theory of everything.' More correctly, string theory is 'A theory of everything.' As current science recognized the five "forces" in the universe: Electricity, Magnetism, Gravity, and the Strong And Weak Nuclear Forces (the latter two deal with what holds atoms and nuclear particles together), scientists found ways to simply things, first showing that Electricity and Magnetism were the same, then connecting the Strong and Weak forces, which leaves Gravity and "All the others". Scientists, from Einstein on, have been attempting to create one description, which will encompass everything -- matter, energy, space, forces, and time. String Theory (with several different flavors) have been proposed as the answer. None have yet held together to answer all challenges. (edit) Goof: when David Bohr's profile was searched on the data base, it shows that he was born on 1970, but the age that is showing on his profile is 20 years old. He should already by 38 years old! (edit) In an interview in the San Francisco Chronicle, October 31, 1996 Grissom revealed that as a boy he collected dead animals he found in his Marina Del Ray neighborhood and performed necropsies on them. (edit) Dr. Al Robbins wears a pacemaker because he has bradycardia. (edit) When CSI Nick Stokes attempts to re-create the conditions that caused a suspect to burst into flames, Jamie Hyneman and Adam Savage of the Discovery Channel's "Mythbusters" are depicted as watching and approving his experiment in the background. (edit)

This episode has an allusion to the popular FOX sci-fi drama The X-Files where the aliens all have green, toxic blood. (edit) Doc Robbins: Doe, a deer. A female deer.

This is the opening line from the Do Re Mi song from the movie the Sound of Music. He obviously uses it intendedly, though David doesn't find it funny. (edit) Willows: (holding a pacemaker) Takes a licking and keeps on ticking.

This was the slogan for Timex watches, combined with torture tests, it emphasied the durability of their product. (edit) Gil Grissom quotes Ian Fleming when he says: "Once is happenstance, twice is coincidence and three times is enemy action." when tying the three deaths together. Fleming had villain, Auric Goldfinger, say these words in his James Bond novel, Goldfinger, and named the three chapters of the book after the three phrases in the quote. (edit) This episode was filled with references to modern physics.

The elderly couple killed by breathing cyanide gas had a cat named Shrodinger. This is an allusion to the 'Schrödinger's Cat thought experiment,' an explanation developed by Austrian physicist Erwin Schrödinger to show the problems associated with the Copenhagen interpretation of Quantum Mechanics. The Schrödinger's Cat paradox showed that, according to the Copenhagen interpretation, a cat sealed in an air-tight box with a Geiger counter and a flask of hydrocyanic acid would be both dead and alive at the same time, until the box was opened and the cat observed.

One green-blooded character in this episode was named David Bohr, while another was named Kyle Planck. Danish physicist Niels David Bohr won a Nobel prize in 1922 for his development of a model for the structure of the atom. German physicist Max Karl Planck, who won his Nobel Prize in 1918, first showed the value of quantum theory through his work on black body radiation.

At the end of the episode, Grissom ties all the seemingly unrelated incidents together by referring to String Theory, an approach to physics that attempts to unify all physical phenomena. (edit)
