I've heard (from anime, and somewhere else that I can't remember) that in Japan there's a practice where some people like to put mayonnaise on pizza. One of these days when no one's judging, I really want to give that a try, because it seems like it would be, if not awesome in a very-bad-for-you way, at least very interesting. I wonder if it works best with specific kinds of pizza (Like, does it have to be some kind of seafood pizza that would be more likely to be served there?), or would any kind of pizza work...?
