The favorite nickname that I ever had was "Rock Man" at summer camp. Swimming was in a deep pond and nobody would believe that I had dived under water to the bottom. To prove that I had, I dove down there again and came up with a large rock. This was greeted with amazement.
Two favorite movie villains that immediately come to mind for me are Heath Ledger as the Joker in The Dark Knight (2008) and Robert Mitchum as the evil preacher Reverend Harry Powell in The Night Of The Hunter (1955).
