Mike Birbiglia, a comedian on Comedy Central, is, in my opinion, one of the funniest comedians on television today. One of my favorite sketches by him, entitled "Goals," is all about how people of different races treat each other.
He starts off his sketch with a jab at the different nicknames people of different races give each other. He makes fun of the way white people are constantly called "cracker" by making it into something that doesn't even register as an insult, but just as a type of food. From this, he moves on to how white people make fun of themselves for being white. A white man himself, Birbiglia only perpetuates the stereotypes that he makes fun of while he makes fun of them.
One of the best parts of this sketch is Birbiglia's rendition of the "white guy doing a black guy doing a white guy" voice. With this voice, Birbiglia explains that everyone makes fun of everyone else no matter what. Different races always find something within another race that is easy to imitate. This voice fits the Zip Coon stereotype where a white person is imitating a black person imitating a white person, but managing to sound ridiculous and silly while doing it.
