A bartender is getting ready to close for the night when a robber bursts in and pulls a gun.
"This is a stickup!" He yells. "Put all your dough in a bag!"
"Don't shoot," pleads the barkeep. "I'll do whatever you say!"
The bartender stuffs all the money into a bag and hands it over.
The crook snatches it and then puts the gun to the bartender's head and says, "All right, now give me a blow job!"
"Anything!" cries the bartender. "Just don't shoot!"
The bartender gets on his knees and starts blowing the guy. After a few minutes, the robber gets so excited he drops his gun.
The bartender picks the gun up off the floor and hands it back to the robber.
"Hold the gun, dammit," he says. "One of my friends might walk in!"
