Part of what led to the end of the Chappelle Show is evident here. Dave started feeling conflicted about the type of humor/language he was using and felt that some in the audience were laughing AT him instead of WITH him.

I've heard certain words used in films and particularly gangster films, and it's never led me to use those words in conversations.That's just me,though.Even if I was the type of person to use those words in real life, I'd have the common courtesy not to use them in public forums where I might offend someone, but again that's just me.
