Afraid of the Dark
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 #1 what he was doing. The patient replied, "Can't you see I'm sawing this piece of wood in half?"
The doctor asked 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 light bulb."
The doctor looked up and noticed Patient #2's face is all red. The doctor asks Patient #1, "If he's your friend, don't you think you should get him down from there before he hurts himself?"
Patient #1 replies, "What? And work in the dark?"
