A man is giving his teenage son "the talk". After describing the more technical details of conception, he goes into describing the beauty of the female form. "And the best part," he says, "is like a beautiful flower. Before having sex, it has an intoxicating scent, soft beautiful folds, and overflowing with sweet nectar." He finishes with a wink.

"Ok," says the son, "but you said thats before having sex. What's it like after?"

The dad replies, " Ever seen a bulldog eating mayonnaise?"
