My favorite part of the movie's when he takes the bike while on the set of the lame movie they were making... Dressed as a nun he goes, "Good Idea, I'm going to start a paper route right now!"
Too funny...

Of course, his losing it on the Harley and going through the billboard was equally hysterical. The Coyote & Roadrunner "Pap!" sound effect when he hits that is incredible.
