Fresh from the shower, a woman stood in front of the mirror complaining to her husband that her breasts were too small. Instead of characteristically telling her it's not so, he uncharacteristically came up with a suggestion.

"If you want your breasts to grow, then everyday take a piece of toilet paper and rub it between them for a few seconds."

Willing to try anything, she fetched a piece of toilet paper and stood in front of the mirror, rubbing it between her breasts. "How long will this take?", she asked.

"They will grow larger over a period of years", her husband replies.
she stopped.

"Do you really think rubbing a piece of toilet paper between my
breasts every day will make my breasts bigger over the years?"

Without missing a beat he says, "Worked for your butt, didn't it?"
