The Miracle of Toilet Paper

Fresh from my shower, I stand in front of the mirror, complaining to my husband that my breasts are too small.
Instead of characteristically telling me 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 your breasts for a few seconds."

Willing to try anything, I fetch a piece of toilet paper and I stand in front of the mirror, rubbing it between my breasts.
"How long will this take?" I ask.

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

I stop.

"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?"
