Best speech in a movie

[Carolina Pirate]

The most quotable movie thread turned out really good but then it got me thinking, what are some of the best speeches or lines in a movie and not just quotable sayings.

There's the "You can't handle the truth" which is great.
"This is Sparta" & "Then we shall fight in the shade" - 300

Tombstone has great dialoge in it but the best speech hands down in a movie goes to........

Gunnery Sergeant Hartman from Full Metal Jacket
