A woman says to her husband that she wants to have plastic surgery to enlarge her breasts.
Husband: "Hey, you don't need surgery to do that. I know how to do it without surgery." Wife: "How do I do it without surgery?"Husband: "Just rub toilet paper between them".
Startled, the wife asks, "How does that make them bigger?"
Husband: "I don't know, but it worked for your ass."
