Body Parts Series
Human feet are the walking parts at the end of the legs tubes. Some pervs have what's called a "foot fetish," which means they like to lick your feet and smell your shoes and weird stuff like that. While God generally disapproves of anything outside the ordinary channels of "vanilla sex," I can't remember any specific prohibitions against foot fetishism in the Bible. For safety's sake, you should probably assume a mild disapproval, however
On the other foot, I have no idea at all how Stephen feels about the feet. Do you know? Until I hear otherwise, I'm going to assume that his position here mirrors his position on ice cream, and recommend that America lick away.
