Favorite movie line?

My all time favorite will always be Rhett Butler's "Frankly, my dear, I don't give a damn."

After getting that on the record, there are several I find popping up in my language in situationally appropriate circumstances.

From Jaws:
Sheriff Brody: "You're gonna need a bigger boat!"

From Independence Day:
Capt Hiller: "I ain't heard no fat lady!"
---
David Levinson: "Must go faster! Must go faster!" (Jeff Goldblum repeating his earlier Jurassic Park line)
---
Russell Casse: "I've been sayin' it... ain't I been sayin' it, Miguel? I've been sayin' it!" and
"Hello, boys, I'm BA-ACK!"

From Men In Black:
Edgar: "You can have my gun, when you pry it from my cold dead fingers."
Bug: "Your proposal is acceptable."
