How many doctors does it take to screw in a light bulb

Question: How many doctors does it take to screw in a light bulb?

Answer: That depends on whether it has health insurance.

Answer: Three. One to find a bulb specialist, one to find a bulb installation specialist, and one to bill it all to Medicare.

Answer: None. They just tell it to take two asprin and come round to the surgery later.

Answer: None. They only sign the death certificate and phone the mortuary.

Answer: None. They would diagnose depression and prescribe benzo diazapines.

Answer: Only one, but he has to have a nurse to tell him which end to screw in.
