I agree with many of them at the top, but as it gets further towards the bottom it seems like they just put whatever they could think of on there. For instance, where's "I'm Spartacus! No, I'm Spartacus!" (or whatever the exact quote is). That's certainly a lot better than "I'm the king of the world" from Titanic.
