Well check out this act by Michael Richards. He must have been out of the spotlight too long since Seinfeld went off the air in 1998 because he just so happened to have thrown some racial epitaphs around in his act. And the aftermath cause some in the audience to get out of that club on this night. And I can't say I'd blame him. Check the video out.
EDIT: FOXNews.com has the story.
PS: I posted it here at first. Whenever I'm not able to post here (thanks to some problems with Blogger) look there. Blogger Beta is proving to be a little bit more reliable.
UPDATE: From BareKnucklePolitics.com and the same video and hopefully more lasting than the other link.
