Chinese guy says, "Give me a jigger, nigra."
Black bartender says, "Yo, man, that's not cool. You can't come in here and say that to me."
The Chinese guy just smiles from ear to ear. "Give me a jigger, nigra."
The black bartender says, "How would you like it if you were behind the bar and I came up and said something like that to you?"
The Chinese guy shrugs, "I don't care."
So the Chinese guy gets behind the bar, the black bartender goes outside, walks in and says, "Give me a drink, chink!"
The Chinese guy says, "I'm sorry, we don't serve nigras in here."
