A psychiatrist was doing his normal morning rounds when he entered a patient's room. He found Ted sitting on the floor, pretending to saw a piece of wood in half. Burt was hanging from the ceiling, by his feet. The doctor asked Ted what he was doing. The patient replied, "Can't you see I'm sawing this piece of wood in half?" The doctor asked Ted what Burt was doing. Ted replied, "Oh. He's my friend, but he's a little crazy. He thinks he's a lightbulb." The doctor looked up and noticed Burt's face was getting very red. The doctor said to Ted, "If he's your friend, you should get him down from there before he hurts himself." Ted replies, "What? And work in the dark?"
