A head walks into a bar and asks the bartender for a drink, and after he is finished, Boom! A torso appears.
So the head asks for another drink and after he finishes, Bang! Arms come out of the torso.
So the head asks the bartender for another drink and when he has finished, Wham! Legs appear.
The head is thinking, “Hey, this stuff is great,” so he asks the bartender for one more drink for the road and Bang! His whole body disappears.
The bartender turns to him and says, “You should have quit while you were a head.”
