Just a head
There is a father who is very proud of his son because he is turning 21.
There is only one thing wrong. The son is just a head. No torso, no arms, no legs, just a head.
His father brings his son to a bar on the night of his 21st birthday.
The father is just gleaming with pride and so he orders a beer for his son. His son drinks up, and poof, magically he has arms.
The father, the son, and the rest of the people in the bar are just amazed. He takes another sip, and poof, now he has a torso. His father cheers him on, telling him to take another sip.
So the son takes another sip and he all of the sudden has an entire body. The father is so proud.
He starts to cry.
The son is kind of disoriented and he staggers out of the bar. He then walks into the middle of the road and is hit and killed by a taxi.
The father just starts crying again. The bartender turns and says to the father, “Boy, he should have quit while he was a head.”
