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?"
