To make you laugh

OK-I promise I won't start posting every joke or funny thing I come across, but this made me laugh so hard..
From Animal, Vegetable, Miracle by Barbara Kingsolver. She overheard her 3rd grade daughter explaining this to some of her friends..
"A stallion is a boy that's really fierce and bossy," she told them. "But they can give them an operation that makes them gentle and nice and helpful. You know. Like our daddies."

So many levels on which this is funny to me.
