Randy: There are certain rules one must abide in order to sucuessfully survive a horror movie, rule number one, you can never have sex.
Randy: Big no-no! Big no-no!
Stu: I'd be a dead man.
Randy: Rule number two, you can never drink or do drugs. [Everyone clacks their beers together.] It's the sin factor. An extension of number one. And number three, never, ever, under any circumstances say "I'll be right back." Because you won't be back.
Stu: Hey, I'm gettin' another beer, you want one?
Randy: Yeah, sure.
Stu: [Dramatically.] I'll be right back!
Randy: Yeah, you bent the rules. I'll see you in the kitchen with a knife.
