Need help identifying this film...

[CurvaParabolica]

...and I know PH love these There is a quote going around my head and I can't remember which film it's from; all I remember it's between two guys arguing:

A: "Do you know what you find if you looked up the word "idiot" in a dictionary?"
B: [taken aback]"Er… a picture of me?"
A: "NO! The definition of the word "idiot", of which you are one!"

I await the speedy replies

I merely highlighted your first quoted line and clicked search...is it worth watching? I don't like Val Kilmer.
