Best movie quotes

[PoBoy321]

Tonight I watched Animal House and Caddyshack, easily two of the most quotable movies of all time. This lead me to this question: What, in your opinion, are the best movie quotes of all time? I think that there are certainly many throughout the years, both comedic and serious, which can be considered great, but I think that everyone has, in their own mind, based on their own feelings and inclinations, what is the best movie quote of all time. I'll give you mine, from Animal House:

[ QUOTE ]
Otter: But you can't hold a whole fraternity responsible for the behavior of a few, sick twisted individuals. For if you do, then shouldn't we blame the whole fraternity system? And if the whole fraternity system is guilty, then isn't this an indictment of our educational institutions in general? I put it to you, Greg - isn't this an indictment of our entire American society? Well, you can do whatever you want to us, but we're not going to sit here and listen to you badmouth the United States of America. Gentlemen!

[/ QUOTE ]

Now, some people could see this quote as just a funny moment in an otherwise hilrious movie. I, however, feel that this quote was actually a rather brilliant satire of the American judicial system which, shortly after Roe v. Wade, turned into a legalistic bastion of sophistry.

Now I ask you, OOT, to present your favorite movie quotes and your reasons for picking it.
