My Favorite Movie Scene of all time ( One of them )

Vizzini: I can't compete with you physically, and you're no match for my brains.
Westley: You're that smart?
Vizzini: Let me put it this way. Have you ever heard of Plato, Aristotle, Socrates?
Westley: Yes.
Vizzini: Morons.
Vizzini: Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the wine in front of me.
Vizzini: You only think I guessed wrong - that's what's so funny. I switched glasses when your back was turned. Ha-ha, you fool. You fell victim to one of the classic blunders, the most famous of which is "Never get involved in a land war in Asia", but only slightly less well known is this: "Never go in against a Sicilian, when *death* is on the line.". Hahahahahah.

I can do this deadpan...please call me if you would like to hear it live
