Some of them are fabulous. Some of them a godawful. I really like the one of Heath Ledger.
The dude dressed as Hitler I just want to smack. Oh, yes he has all these 'it could be any one of us' explanations, but he's really just doing it to get noticed (which has been hugely successful!), and all I can say is HOW DARE HE?!
