Heh, a classic. Granted, I never knew the ENTIRE speech whenever I quoted it, but at least I knew the movie.
And now a few from an ill-fated cartoon series.
"Who is driving? Oh my god, bear is driving, how can that be?"
Randal: Do you think Phantom Menace is as good a movie as Empire?
Lucas: Well, certainly, I, uh, I think it's the best movie I've made yet.
Randal: Permission to treat this witness as hostile. Mr. Lucas, how do you explain that in Star Wars Obi-Wan tells Luke that when he met his father he was a great pilot, but in Menace he's just a little kid?
Lucas: Well, uh, my kids thought...
Randal: And how come Obi-Wan tells Luke that Yoda is the Jedi that trained him, but in the movie Liam Neeson trains him?
Lucas: Um, well, the power of myth...
Randal: Isn't it true you knew this was a bad movie, that you wrote it over a weekend but told people you had it written for years!
Lawyer: Objection! The pod race was pretty cool...
Randal: No further questions, your honor. (to Lucas) I want my eight bucks back.
