CSI: Crime Scene Investigation

Grissom: And I don't want to hear any rumors that Paul is dead... Grissom might be talking about not wanting the beetle he and Sara are looking at to die since it might hurt the case, but he is alluding to "Paul is Dead", the most famous hoax surrounding The Beatles. In the late 1960s, rumors circulated that Paul McCartney died and he was being replaced on stage by a look-alike. People began claiming that evidence of his passing could be found in lyrics and album artwork, such as the cover of Abbey Road being his funeral procession.

Sara: Flies don't spontaneously generate. When the theory of evolution was in its infancy, Lamark, Darwin's predecessor suggested that simple life forms, like maggots, spontaneously came into existence. He was later proven wrong by Francesco Redi, who proved that maggots don't appear when flies are isolated from the meat.

Doc Robbins suggests "Jaques Cousteau" as the name of the dead man in a tree- in a reference to the famous scuba diver.

Grissom: Right through his Jimmy Durante. Jimmy Durante was a famous actor/comedian known for having an oversized nose.

Nick: Leggo my Greggo! Nick makes a reference to the slogan of popular breakfast food, Eggo Waffles. The actual slogan is "Leggo my Eggo!"

Episode Title: Scuba Doobie-Doo The title of this episode is a play on the popular cartoon character Scooby Doo, whose trademark line is "Scooby-Doobie-Doo".
