One day, fresh out of the shower, she is yet again in front of the mirror, now complaining that her breasts are too small.

Uncharacteristically, the husband comes up with a suggestion. "If you want your breasts to grow, then every day take a piece of toilet paper, and rub it between your 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 her 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 toilet paper between my breasts every day will make my breasts grow over the years?"

The husband shrugs, "Why not, it worked for your butt, didn't it?"

(He lived, and with a great deal of therapy, he just might be able to walk again.)
