This gay guy walks into a bar, and sits down at the bar next to a black dude. After a couple of minutes, the gay guy leans over to the black guy, and says, "Hey, how about a blow job?
Immediately the black guy whirls around and smashes his beer over the other guy's head. He knocks the gay to the floor and proceeds to kick the s*** out of him and drags him, unconscious, out of the bar onto the street.
The black guy then returns to his stool and sits down. The bartender says, " Holy smokes! What the heck was that all about? I've never seen you so upset! What did he say to you?"
The black guy says, "I don't know, something about a job."
