Gosh, I've seen pics of walls with pits before. In fact, I've seen them since the last time this was brought up.
What's important to note, even woma pythons have pits. They're just really, really reduced.
Edit: This may not been the pic, but this does seem to have one pair of pits. http://www.spitfirereptiles.com/sphp...4-0901.med.jpg
