When Zelda was growing up, her mother used to tell her, "Girl, someday you'll find out that a man's brain is in his pants, dangling between his legs."
When Zelda reached the appropriate age she started dating. On one of her dates she came home late. Her mother was waiting up for her and as soon as she entered the house the mother asked Zelda, "That boy you went out with today, what's he like?"
"He's a nice guy, but his brain's too small and he can't use it long enough to satisfy me."
