An elderly woman arrives at the supermarket checkout line with bread, milk, peanut butter, and 21 cans of cat food. "Got a lot of cats at home?" says the cashier, smiling. "Cats? Oh no dear! I'm allergic," says the woman. "These are for my husband. it's all he will eat." Shocked, the cashier says, "You feed him ONLY cat food? You can't do that! He'll die!" "I've been feeding him cat food for 50 years and he's absolutely fine thank you very much! Mind your own business!" says the woman, and leaves in a huff. A week later the same elderly woman approaches the same cashier with bread, milk, peanut butter, but no cat food. The cashier notices and says, "No cat food this week?" "No!" says the woman. "My husband's dead!" "I'm sorry," says the cashier, "But I told you eating nothing but cat food would kill him." "For your information, it wasn't the cat food," says the woman. "He was licking his balls and fell off the roof."
