Star Wars hypothesis:

You never see anyone go to the toilet, but R2 units are following people around and all over the place. They are Poop Droids, the domed top flips up and there is a seat, they are designed to communicate through beeps because nobody wants to hear them complain when a Wookie uses them.

My 10 year old son hates this idea with a passion.
