A reporter interviews a psychiatrist in a mental asylum.
REPORTER: Doctor, how would you know if a person has to be admitted?
DOCTOR: We fill a bath tub with water. Then, we give the patient a spoon, a cup, and a bucket. Then we ask the patient to empty the tub.
REPORTER: Aha! That’s an ingenious test. A normal person would, of course, use the bucket!
DOCTOR: No. The normal person would pull the drain plug. Now, do you want a private room or a ward?
