Walmart would sell the hair off a man's back, and at a good price, if there was a market for it.
It's creepy, yes, but keep in mind they aren't selling these in stores, just on the website. It would definitely be a mistake to sell these in stores, as you'd offend a lot of people with the negative response these can elicit. Then again, they sell the X-Box 360, which is sure to die pretty quickly.
