I've never really felt a need to harass someone over some personal characteristic they can't control. But I have a dry enough wit to understand the humour in almost anything, even racially based things. My cousin though isn't so tolerant. He thought he was being a nice guy and took a black co-worker water skiing on the Savannah River. He was pleased with his demonstration of racial tolerance until the local marine patrol boat stopped him and the officer gave him a citation for trolling for alligators out season.
