A woman stares at her breasts in the mirror. "I think my breasts are too small! I want a bigger pair!"
Her husband overhears her and walks into the bathroom. "Ok dear, here's something you could try. Take a piece of tissue paper and rub it between your breasts a couple of times, every few hours, every day."
She looks at him strangely. "I really think it works" He says. "How the hell is that going to help my breast size!?" She exclaims.
He turns to her and says "Well it worked for your ass didn't it?"
