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?"
