A doctor of psychology was doing his normal morning rounds when he entered a patient's room. He found Patient #1 sitting on the floor, pretending to saw a piece of wood in half. Patient #2 was hanging from the ceiling, by his feet. The doctor asked patient number 1 what he was doing. The patient replied, Can't you see I'm sawing this piece of wood in half? The doctor inquired of Patient #1 what Patient #2 was doing. Patient #1 replied, Oh. He's my friend, but he's a little crazy. He thinks he's a lightbulb. The doctor looks up and notices Patient #2's face is going all red. The doctor asks Patient #1, If he's your friend, you should get him down from there before he hurts himself Patient #1 replies, What? And work in the dark?
