I'd have to think about this for a second.
"Search your feelings, you know it to be true!" -Empire Strikes Back
-The entire South Park movie - "Do you have the buttfor?" "What's a buttfor?" "For. Pooping."
-"She would ask herself silly questions, like, how many couples are having an orgasm right now?" *montage of orgasming couples* "Fifteen!" -Amelie
-"Franklin did this, and Franklin did that, and Franklin did some other damn thing. Franklin smote the ground, and out popped George Washington, fully grown and on a horse, and together the three of them, Franklin, Washington, and the horse, conducted the entire revolution on their own." "I like it." -1776
-Most of Kick-Ass - "Who are you supposed to be, the Green Condom?"
-*ear-piercing note* "What was that?" "B flat." -Victor/Victoria
-"What the hell is a Pirin tablet?" "It's aspirin, just with the A and the S scraped off." -The Birdcage
-Really, all of the Birdcage.
-"I'll turn him into a flea! A harmless little flea! Then I'll put that flea in a box, then I'll put that flea in another box, and then I'll mail that box to myself, and when it arrives.... I'LL SMASH IT WITH A HAMMER! It's brilliant!" *knocks over poison* "...or, to save on postage, we'll just poison him with this!" -The Emperor's New Groove
-Johnny Depp's speech about immortality from The Imaginarium of Dr. Parnassus: "All those people... they're all dead." "Yes, but... Immortal, nevertheless. They won't get old or fat. They won't get sick or feeble. They are beyond fear... Because, they are forever young. They are gods. And you can join them. Prepare to be reborn. And remember... Nothing's permanent... Not even death." This just hit me hard because you could tell it was in reference to Heath Ledger.
-"Of course I'm serious! And don't call me Shirley!" -Airplane!
-Really, all of Airplane! as well.
-All of Galaxy Quest - "By Grabthar's Hammer... what a savings."
-"I gave all my clothes to the poor." "What about... those?" "Oh, the poor didn't want these." -The Sound of Music
-All of the original Producers - "I'm pain! I'm in pain, and I'm wet, and I'm still hysterical!"
-"Screw Max!" "I do." "So do I." -Cabaret
-"We should have bought a squirrel." -along with everything else from Rat Race.
