I don't really get why you'd want to call your black friends crazy niggers to begin with. I mean there's a context for that kind of thing I don't censor myself around my black friends, but it never occurred to me that calling them racial slurs would somehow be comedic or clever. But then neither is Robobo or whatever it was called.
Real friends aren't going to get too bent out of shape over that kind of thing, but it doesn't really mean they appreciate it either.
