A woman in the bar says that she wants to have plastic surgery to enlarge her breasts. Her husband tells her, "Hey, you don't need surgery to do that. I know how to do it without surgery."

The lady asks, "How do I do it without surgery?"

"Just rub toilet paper between them."

Startled the lady asks, "How does that make them bigger?"

"I don't know, but it worked for your ass."
