That's disgusting. Why can't people clean up after themselves?

You see it out in the public restrooms a lot, accompanied with a load in the porcelain potty.

They should install a funnel and tube for all the idiots that don't have enough sense to lift up the seat.

This ticks me off more than almost anything. Dude - either use a urinal, or lift up the freakin seat. If you don't want to use your hands, lift if up with your foot. If still that is too much for you, then be careful with your pee - there is no need to go all over the place unless you are blind or completely intoxicated, which I doubt is the case in a public restroom in the middle of the afternoon. Now, because of your classless behavior, I have to use a bunch of tissues and wipe your pee of the toilet seat with my hand before I sit down. If there is one invention I hope to create, or at least contribute monetarily towards its creation, it will be this - a sensor that goes off when someone pees on a seat. What this sensor will do will cause the toilet to spit water all over the culprit's face and clothes.
