Who were the nicest/nastiest celebrites you've met?

Met Brian Setzer in 1984 while swimming in Quincy Jones' pool with Quincy Jr. and another friend. Brian was a creep and I won't repeat what he said to us. I have also met Ric Flair in Hong Kong in 1991. He was a decent guy and defeated the Chinese national Greco-Roman wrestling champion in an exhibition match.
