Goof: When Nick and Grissom enter the mine, they turn on their flashlights. In the camera angles facing them, they have medium sized flashlights, but in the shots looking at them from behind, they have very large sized flashlights.
(The victim has a stake embedded in his skull)
Nick: Sharp force trauma?
Nick: There's a sucker born every minute.
Grissom: Yep, and they all come to Vegas.
(In a mine)
Grissom: Are you seeing this?
Nick: Gold. We're rich.
Grissom: I'm not so sure.
Detective Cyrus: Death: the cheapest show in Vegas.
Grissom: Yeah. It doesn't surprise me. Remember the MGM fire? We found people burned to their slot machines cause they wouldn't leave the action.
Detective Cyrus: Only in Vegas.
Nick: Under the fingernail?
Grissom: Yep. (Nick looks up with pained expression)
Nick: He wiped his own ass?
Grissom (laughs): No, Nick, it's not human. It's scat. Could be from a bat.
Nick: Bat scat.
Grissom: Bat 'guano'.
Grissom: Bats are like bees, Nick. Don't bother them, and they won't bother you
Nick: Let's not bother them... I mean it
(Nick and Grissom approach an old mine)
Nick: What's with the gate?
Grissom: It's a bat gate. Keeps people out, lets the bats in. Old mines are considered bat habitats and preserves.
Nick: Who puts the bat gates in?
Get Free - The Vines (played at the beginning during car chase)
Stray Cat Strut - Stray Cats
No Sugar Mama - The Von Bondies
Warrick: I don't think I can handle another dead kid right now.
This refers to the events of the earlier season episode "Random Acts of Violence" where a friend of Warrick's has his eight-year-old daughter killed in a drive-by shooting.
