Brad, it's called humour. When Oprah Winfrey asks Billy Crystal to do black shtick comedy it's because it's funny, not because she likes being offended. I had a teacher in high school who stood on his desk waving a sword and reading King Henry's famous speech on the eve of battle. I had another who made us memorise passages from the Illiad. Guess which one I can recite at a new Age California coffeeshop in my Birkenstocks while sipping herbal tea?
