Johnny Rotten. He's a big fan of mine. I used to see him out in the audience in England and he'd stand up and holler. He's funny. Smart too and a nice guy. Don't think he's a jerk because he isn't.
I'm sick to death of famous people standing up and using their celebrity to promote a cause. If I see a particular need I do try to help. But there's a lot that can be achieved by putting a check in the right place and shutting up about it.
