This one is going to be one of my all time favorites. CLASSIC! I'd use it for a screensaver, but my boss would think it was about him, and then try to screw me over.
I am totally slack-jawed speechless over this. The closest I've been to this IRL is when a colleague did not realize he was having a very angry disagreement with some cleverly edited tapes of himself. He thought he was talking to a complete idiot. He was right.
