I want someone to invent a toilet with a scale in it that will weigh my poo before I flush and send it out to sea.
It would also be sweet if it was programmed to play song clips related to the weight of your submission. For example, let's say you dropped off ten pounds of kids at the pool (I blame the Mexican food) . . . the digital scale would register a whopping ten pounds and then the built-in iPod would play a short clip from Rod Stewart's Young Turks, "Patti gave birth to a ten pound baby boy, yeah!"
That would be awesome.
