I’m just amazed that

A. People have to be told to wash their hands.
B. They actually have to be taught how.

Then there are the clowns who take a piss in a public washroom, go to the sink and turn on the water with one hand, rinse the two fingers they used to hold their dick and call it good. Though they are more evolved than the ones who wipe their ass after a crap and head straight for the door.
