Fresh from her shower, a woman stands in front of the mirror, complaining
to her husband that her breasts are too small. Instead  of
characteristically
telling her it's not so, her husband uncharacteristically 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 will grow larger over a period of
time," he replies.

The wife stops. "Do you really think rubbing a piece of toilet paper between
my breasts every day will make my breasts larger over time?"

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