A married lady visited her elderly parents' home. When she opened the refrigerator, she was shocked to see inside a picture of a young, lovely, slender bikini girl. "Mom, who's this?" asked the lady. "Oh, I put that up there to remind me not to overeat," replied her mom. "Is it working?" "Yes and no," said her mom. "I've lost 8 kilos, but your dad has gained 20!"
