Pretty much all of the dialogue between Beck and Travis.
If it's possible to have a single line count as a Big Lipped Alligator Moment, it would be this one: "...That's a lotta cows."
"Not this boy's pintu. Uh-uh!" (hastily pulls his pants back up)
The entire "I have to pee" sequence, but this bit of dialogue sent this troper into hysterics:
Travis: If you want to get out of here, you're gonna have to carry me and I guarantee I'm gonna pee on your head.
Beck: You threatenin' me? You're threatening me with pee?
Mariana flipping off Hatcher and his brilliant response of, "If I was ten minutes younger..." which is incredibly justified considering it's Rosario Dawson.
