In actuality, jokes about movies aside, I *have* seen toilets with three buttons. One for a water spray, like a bidet, but integrated in the toilet; one for a jet of hot air for the drying of stuff after the water jet, and one for flushing. They could, easily, be given a shell shape.
Aside from that, there's an old joke about first class women's toilets on air planes; I've only ever heard it in Dutch but I assume it exists in English as well. One button for a spray, one for perfume, one for automated tampon removal and replacement.
