If you had 3 legs with the accompanying 3 buttocks, do you think you would have a bum hole in both the valleys, or just in one? And which crack would it be in? Would it be random or would left handed people have a left bum hole and righties a right bum hole?
And if the extra leg is central, would the big toe be in the middle of the 5, or would there be a big one on each end?
Or maybe the third leg comes out the back at the bottom of your spine and goes backwards so you stand like a tripod, and if so would the foot on it face backwards?
