Great line: "Who's the bigger fool -- the fool, or the fool who follows him?"

It's from "Star Wars" (aka "A New Hope" -- you know, Episode IV?), which I've been watching ever since I got back to the office after my city council meeting. 

Obi Wan Kenobi is full of great wisdom for geeks.

What's your favorite movie line -- Obi Wan's or otherwise?
