A white man walks into a bar and says to a bartender "Hey nigger. Gimme a beer". The bartender says "Don't say that to me. What happened if I said something like that to you?". "The white man says "I don't know lets find out". They switch places. The black comes in and said "Hey honkey, gimme a f*ckin' beer". The white man says "Sorry. We don't serve niggers"
