Losing weight

One time when I was home visiting my folks, my mom asked me to set the table for dinner. I opened the refrigerator and taped to the inside of the door was a risque picture of a lovely, slender, perfectly built, but scantily-clad young woman.

"Mom, what's this?" I asked.

"Oh, I put that up there to remind me not to over-eat," she

"Is it working?" I asked.

"Yes and no," she explained. "I've lost 15 pounds, but your
dad has gained 20!"
