Where do babies come from?

Your mother. No, wait, my mother.

Well, when a stork and a cabbage love each other very much, they get together and have sex. Then the half-strings of DNA from the stork combine with the half-strings of DNA from the cabbage, and that produces a fetus. The stork takes the fetus, in the dead of the night, and visits a woman and puts the fetus into her uterus, or "baby oven," as the scientific community calls it. There, the fetus grows to a manageable size, about the size of a softball. Then it eats its way out of the woman's stomach and skitters off into the ventilation ducts, where it needs to be hunted down and killed before it can grow to full size. This is usually accomplished by a girl with an underbite, in her underwear.

That was from memory -- I really need hobbies, man.
