Joel, Nick and Andy refer American composer and pianist John Tesh as one of their own: a caveman.
When Andy and Nick are checking the mail, Andy is holding a ribbed noodle. The scene cuts to Andy and Nick walking into their apartment and Andy is holding a round noodle.
When Thorne calls him, Andy is glazing a ham: a reference to "The Cavewoman" when Andy mentions his personal obsession with the "Great Ham Craze of '96."
The car Andy drives is a VW, but the logo is taped off.
Andy: There are a lot of hot babes living here, Nick.
Nick: Yeah, if you like bleached-out silicone stuffed cougar pups.
Andy: I do.
Nick: Poor Joel, you're like a moth that just keeps hurling itself at a screen, unable to accept the fact that it's never going to get into the house.
Joel: Moths get into houses all the time.
Nick: Fine, something bigger, like a grizzly bear.
Andy: No, a bear doesn't work because it could just burst right through the screen. You got to get something small like a hummingbird.
Nick: Why would a humming bird wanna get into a house?
Andy: Because there's nectar inside.
Joel: I just wanna relax.
Nick: What could be more relaxing then closely examining another man's features?
Nick: Good morning, traitor.
Joel: Good morning.
Nick: Sleep well, traitor?
Nick: Where'd you get those business cards? Traitor Joe's?
Joel: Oh so the plan is to work the word "traitor" into every sentence.
Nick: No… Traitor! Uh-oh, changed my mind.
