Smelly Feet Gag

As with any other part of the body, feet can smell bad. However, because people nowadays tend to stuff them in shoes and socks all day and never expose them to light or air until it's time for a bath, shower, swim or bed, they tend to spend most of their time stewing in their own rancid sweat. This has given rise to the idea that feet are naturally smelly when actually bare feet don't smell any more than any other patch of skin. In reality, that smell is from the literally hundreds of different types of bacteria and fungus that love to live in the warm dark sweaty interiors of shoes. In fact, as boxers and other people who must exert themselves with their hands inside closed gloves can attest, you can develop the same smell in your hands by the same principle. But there is something oddly entertaining about the idea of smelly feet and it's been one of the most common tropes in family-themed media. Children find the concept of smelly feet to be humorous, as evidenced by the popular children's song "Trick or treat/Smell my feet/Gimme something good to eat." Even babies seem to find smelly feet funny; a common game parents sometimes play with their babies is to pretend to smell their baby feet and booties. Truth in Television, indeed.
