How you pee can tell you a lot about exactly what kind of a man you are. Are you a pessimist, Optimist, etc... Pretty clever and funny picture.

Funny picture sign to all those people who might be a Optimist, Pessimist, or a Realist and if you do consider yourself to fall into one of those categories, well I guess you just lost out on some water. And if you don't get this joke it is about the glass being half full or half empty.
