After weeks of prodding, he tells her to wipe toilet paper between her boobs every day and they will grow. The housewife is doubious but tries his treatment nonetheless. Every time she nags, he tells her to use the tp and her boobs will surely grow.
Months later she re-measures herself and is dissapointed to find that nothing has changed. Frustrated, she confronts her husband.
"I feel stupid!" she cries. "Every day for the last four months I've rubbed toilet paper between my boobs, and they haven't budged!"
"I don't know what to tell you," he replies. "It's been working like a charm on your ass."
