The day that this episode began filming, a real forest fire broke out nearby. The directors took the opportunity and ordered some shots of the rescue effort, which resulted in the shots of helicopters dropping water over the fire.
Goof: When Nick and Catherine are interviewing Walden, Catherine's fringe moves from right to left and back to right. This continues throughout the interview.
Goof: The flashback showing the cigarette delay device being set up shows the cigarette being placed deep inside the matchbook. The heat won't set off the matches from there. It should be up near the heads of the matches.
Goof: During demolition of the walls, no masks were worn.
Nick: You just made yourself useful, my friend.
Greg: Oh yeah?
Grissom: You never get a second chance to make a first impression.
Sara: A square of nine dots on paper and you can only draw four lines to connect them... without the pen ever leaving the paper.
Grissom: Right. Think outside the box.
Grissom: Mr. Renteria, your apartment walls are covered in human blood. Are you aware of that?
Clifford Renteria: Yeah.
Grissom: Do you have an explanation?
Clifford Renteria: It's my blood.
Grissom: Your blood?
Brass: You got a stigmata?
Clifford Renteria: No. I get nosebleeds.
Detective O'Riley: Hey. I don't even know where to start with this one. Take a look at that. A scuba diver... up a tree.
Catherine: How the hell he'd get up there?
Grissom: For all we know, this is animal blood.
Brass: Yeah, sure. Deer, sheep, llama.
Grissom: A deer hunter comes home from the mountains drunk decides to play butcher clean his kill. Chops his game up into oven-sized pieces for the winter. I mean, what does he care? He's renting.
Catherine: Hey, coffee boy. Where's my DNA? Cigarette butt? Match book time-delay device? Hair spray? Any of this sound familiar?
Greg: Bags under the eyes, coffee cups, stress face. Any of this look familiar? I'm working on it.
Catherine: Did Grissom put his stuff in front of mine?
Nick: Rocket man.
Catherine: Yeah. Got to love this job.
Catherine: Well, they only get us something if they match Walden's ninja coffee table.
Grissom: Yeah, well... as it turns out our guy stands very close to the wall and blows almost sideways.
Warrick: This is unreal. You actually saw him do this?
Grissom: Right through his Jimmy Durante. Ambidextrous, both nostrils.
Sara: Great. Our big murder is a nosebleed.
Sara: What are we looking for exactly?
Grissom: Same thing we're always looking for; evidence to a crime scene.
(Seeing a bug at a crime scene)
Grissom: Dermastidae masculatus.
(Suspect looks confused)
Sara: That's Latin for "You're hiding a dead body."
(Catherine is walking by DNA)
Greg: Hey! Yo, Cat!
Catherine (she walks into DNA): I'm going to forget you called me that.
Grissom: Two things that have nothing to do with each other.
Sara: Or everything.
(Sara walks out to find Grissom pacing furiously)
Sara: You okay?
Sara: Excuse me?
Grissom: Normally my pulse is seventy, when it gets up to ninety-five, I realize just how mad I am. I- I have ten people working around the clock on this thing.
Sara: You're too hard on yourself.
Grissom: No, no. I'm not mad at me. There's a body in there and that guy knows where it is!
Sara: So what's your pulse at now? You wanna... take a walk around the block? Get some air.
Sara: Clear your head.
Grissom: I'm fine.
Sara: Okay. (touches his cheek, he looks surprised) Chalk... from plaster.
Grissom (rubs his face): Oh.
Sara: Better go wash up.
Catherine: So I suppose you believe in Santa Claus?
Nick: After this... oh yeah.
Nick: Hey, leggo my Greggo!
International Episode Titles:

Judas - The Charlatans.
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 could possible be a reference to three different things.
First it is a play on the popular cartoon character Scooby Doo, whose trademark line is "Scooby-Doobie-Doo".
Second, it could be a nod to the Frank Sinatra song, "Strangers in the Night" which contains the scat line, "Dooby dooby doo".
Lastly, though most obscurely, it could also reference a poem turned song by Shel Silverstein entitled Floobie Doobie Doo."
