Dumb & Dumber
[While driving through Nebraska]
Harry Dunne: I expected the Rocky Mountains to be a little rockier than this.
Lloyd Christmas: I was thinking the same thing. That John Denver's full of ****, man.

Anchorman: The Legend of Ron Burgundy
[Reading off the newsroom teleprompter]
Veronica Corningstone: For the entire Channel 4 news team, I'm Veronica Corningstone.
Ron Burgundy: And I'm Ron Burgundy. Go **** yourself, San Diego.

Dodgeball: A True Underdog Story
Cotton McKnight: I'm being told that Average Joe's does not have enough players and will be forfeiting the championship match.
Pepper Brooks: It's a bold strategy, Cotton. Let's see if it pays off for 'em.

From one of my favorite Hepburn & Tracy movies. Who am I kidding, they're ALL my favorites, but this scene is more memorable than most:

Bunny Watson: You're a sketch, Mr. Sumner.
Richard Sumner: You're not so bad yourself.
