Says Bill Cosby:
They're standing on the corner and can't speak English. I can't even talk the way these people talk: 'Why you ain't. Where you is.' You used to talk a certain way on the corner, and when you got in the house, you switched to English. Everybody knows that at some point you switch to English, except these knuckleheads."
Bill Cosby gets super un-PC in regards to blacks.
