That Thing

A mom of an eight year old boy is awaiting her son's arrival from school. As he runs in, he says he needs to talk to her about making babies. He claims he knows about the development of a fetus, but doesn't understand the answer to the million dollar question. Namely, how does the sperm get into the woman?

The mom asks the boy what he thinks the answer is. The boy says that the sperm is manufactured in the man's stomach, rises up to his chest, then throat, and into his mouth, where he then kisses the woman and deposits the sperm into her mouth.

The mom tells her boy that it is a good guess, but it's wrong. She gives him a hint by telling him that the sperm comes out of the man's penis. Suddenly, the boy's face becomes quite red and he says, "You mean you put your mouth on that thing?"
