A doctor of psychology was doing his normal morning rounds, and he
entered a patient's room to find his patient sitting on the floor,
sawing at a piece of wood with the side of his hand. Meanwhile,
another patient was in the room, hanging from the ceiling by his
feet.
The doctor asked his patient what he was doing, sitting on the floor.
The patient replied in an irritated fashion, "Can't you see I'm sawing
this piece of wood in half?"
The doctor inquired, "And what is the fellow hanging from the ceiling
doing?"
"Oh. He's my friend, but he's a little crazy. He thinks he's a light
bulb."
The doctor asks, "If he's your friend, don't you think you should get
him down from there before he hurts himself?"
"What? And work in the dark?"
