A man has a son who miraculously survives as only a head.
For his son's
21st birthday, the man takes him to the local bar to have his first drink.
As his son finishes his first bottle through a straw, an amazing thing happens. A lump sprouts from under his head and a body grows almost instantly before the man's eyes!
Confounded with this new development, the man gives his son 4 more beers. Although rather drunk, his son became a normal person before his very eyes.
Of course, now the man is curious. What would happen if he gave his son another beer? Would he grow some kind of third arm? Would he become very well endowed? He decides to find out.
As his son finishes the beer, he bursts into flames and disappears completely.
As the man sits, stunned, a drunk leans over and says, "stuff, man, he should have just quit while he was a head"
