Well, I've got a couple from probably the dumbest movie of all time: Gigli (with J-Lo)
Det. Stanley Jacobellis: Man, you know what I'd love to do, right now? Go down to Marie Callender's, get me a big bowl, pie, some ice cream on it, mmm-hmm good! Put some on your head! Your tongue would slap your brains out trying to get to it! INTERESTED?
--------------------------------------------------------------------
Ricki: It's turkey time.
Larry Gigli: Huh?
Ricki: Gobble, gobble.
--------------------------------------------------------------------
Det. Stanley Jacobellis: Your door's not thick enough to pretend you're not home when you're home.

Brian: She's like the ones at the Baywatch. They make my penis sneeze.
