When I was a kid I'd always hated Kool Whip, so it was no trick for a friend to convince me that Kool Whip was made from whipped beef fat. Imagine my embarassment when years later I was telling my in laws about why I wouldn't eat it and even went so far as to get a tub out of the fridge to read the ingredients, which of course included absolutely no beef fat.
