Toilet paper
A woman says to her husband 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." She asks,
"How do I do it without surgery?" Her husband answers,
"Just rub toilet paper between them."
"How does that make them bigger?", she asks.
"I don't know, but it certainly worked for your ass."
