Fresh from her shower, a women stands in front of her mirror, complaining to her husband that her brests are too small.

Instead of his standard response of reassuring her that wasn't the case, her husband uncharacteristically comes up with a suggestion. He tells her "If you want your breasts to grow, take a piece of toilet paper and rub it between you breasts for a few seconds."

Willing to try anything, the wife fetches a piece of toilet paper and stands in front of the mirror, rubbing it between he breasts. "How long
will this take?" she asks.

"They'll grow larger over a period of years," he replies.

The wife stops. "Why do you think rubbing a piece of tiolet paper between my breasts everyday will make my breasts grow over the years?"
