Panel 3 is one of the best drawings of myself I ever did. Yes, I’m aware that in it I look insane.
The tall chair thing is something LBJ used to do. He had a specific chair, in which only he was allowed to sit, installed in Air Force One. It, and the desk in front of it, were designed so that he could adjust their height, ensuring that he would tower over the people seated around him.
Also, if you look at the desks on late night talk shows you’ll see that the host’s seat is always higher than the guests’ chair. Andy Kaufman made a joke about it in a PBS special once. (Think about that for a moment. There was a time that Andy Kaufman was doing specials on PBS!)
