Where I used to work, there was a guy who looked a lot like Jack Black. He thought himself to be quite the cocksman and tried to lay everything in sight, as well as talking (loud on the phone) about attributes of the surrounding female employees. He was also pretty much dumb as a box of rocks, but again thought he was really smart. His name was "Shallow Hal", to most people.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
