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

The doctor inquired 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

Patient #1 replies, "What? And work in the dark?"
