Parents have a child who was born with no body--just a head. He starts growing up, is very intelligent--precocious actually--but still, no body.

One day their pediatrician calls with exciting news: he's located a body that'll be a perfect fit for their kid. And, it's his eighth birthday!

The parents rush into his room and tell him they've got an absolutely great birthday present for him, and are going to surprise him with it.

The kid looks up from his computer game and says, "As long as it's not another f***ing hat."
