Not really a joke, but funny?

That is funny! But what I don't get is why someone would actualy spend money on a piece of bathroom equipment that heats their s? Moreover, purified AIR? From a toilette?? The air is going to be stinky anyway because people fart when they have to go. And then to have an automatic cleaning service to go with it?? Ridiculous. Soap and water can do the same job for less, and probably a better job, too! ARGH! Peole these days. What gives?
