This is just too funny! It’s a skit about a white family with an unfortunate last name which sounds just like a terrible racial epiteth, “Niggar”.
Dave Chappelle is a master at getting a laugh out of race issues. He’s testing the boundaries of racial issues and finding laughs.
If you like this video, I suggest you check out Chappelle's Show - Season 1 on DVD. His most memorable skit is the one in which he plays Clayton Bigsby, a white supremacist who is both blind and black, only he doesn’t know he is black because no one ever told him.
