Asked my wife once, back when we were dating, if she had a certificate of responsibility for that thing as it's killed more men than just about anything in history!
Little boy and girl playing out in the sandbox, little boy stands up and shows the little girl his penis asking if she had one of them too. Little girl stands up and looks, doesn't see anything and runs into her house crying. Little while later, the little girl comes out of her house skipping and smiling. The little boy asks her why she's so happy? The little girl pulls down her pants and shows the little boy her vagina and tells him that her mommy told her with one of these, she can have all the penises she wants!
