Fresh from her shower, a lady 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, he 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 them for a few seconds."

Willing to try anything, the lady fetchs a piece of toilet paper and stand
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," the husband replies. she stops. "Do you really think rubbing a piece of toilet paper between my breasts every day will make my breasts larger over the years?"

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