Ironically, "Ghost World" was one of the few films in which Steve Buscemi didn't get ghosted. This is quite the compilation of Buscemi endings, and it's probably worth mentioning a SPOILER WARNING, just in case you plan on watching any movie Buscemi has ever made.
Some YouTube commenters (society's lowest rung) seem to think it's somehow humiliating to be killed by Christopher Lloyd, but these people are too blinded by Doc Brown to remember that Lloyd has a history of being a badass. Remember his evil Klingon villain in Star Trek III? And, more importantly, as Judge Doom? Shit, that's still horrifying. "Remember me, Eddie? When I killed your brother, I talked... just... like... THIS!"
