I heard a funny joke about that though.
These two businessmen are taking a leak in the bathroom at work. They finish up at the same time, and one heads for the sink and one heads for the door. The one going to the sink says "You know, I went to Harvard, and they taught us to always wash your hands after using the restroom". The one going out the door says "Really, I went to the Community College in my hometown, and they taught us not to piss on our hands."
