Well, really, anyone who DOESN'T do that is living in a world with inferior pizza, and who wants to live in that world? (Says the girl who recently realized she compulsively makes sure that her last bite out of a handful of M&Ms must be 3-4 pieces of all different colors.)
haha! and I completely understand your need to have different colored M&Ms because, going back to the pizza issue, I prefer each bite to have a little bit of each topping. So naturally I would have to arrange my topping before cooking! I think we are one in the same, my friend.
