Regular, normal non-important people insure things that are worth a lot to them— like houses, cars, spouses, and jewelry—to protect against the financial ramifications of that special something or someone getting damaged. So, when a person makes a living from a specific body part, it follows that they (or their employer) would probably want to insure that part. For example, "master ice cream taster" John Harrison samples over 50 packages of ice cream for Edy's Grand Ice Cream (known as Dreyer's west of Colorado) each day, so the company had his taste buds insured for $1,000,000. (Note to self: look into a career in ice-cream tasting.)
So, it only makes sense that some celebrities would want to insure their money-making body parts so they won't be penniless should something happen to their most valuable asset—even if that asset is literally their ass.
Celebrities insuring body parts isn't a new trend—Bette Davis' waist was so small (21 inches) that she reportedly had it insured by Lloyd's of London for $28,000 in case she gained weight. And in 1940, MGM had Betty Grable's legs insured for $1 million.
Here are 21 celebrities with very, very valuable body parts.
