On Chappelle Show? Well, still, that quote is straight out of Quentin's character in PF. Spike doesn't like films where white people have free reign to use the word and Quentin makes film that reflect culture in a way, so he doesn't give a fuck about the use of the word. To Spike, it's racist to hear a white person use the word. To anyone with a functioning brain watching, it's Quentin's portrayal of people as well as the times because the man clearly isn't racist. But Spike considers any use of the word by white folks to be racist. That's how up his butt he is.
