In a "Mental Hospital" a journalist asked the Doctor: How do you determine whether to admit a mental patient or not?
Dr "Well, we fill a bathtub with water and then give the patient:
(a) a teaspoon
(b) a glass
(c) a bucket,
and ask them to empty the bathtub.
Journalist "Oh, obviously a normal person would use the bucket because its bigger."
Dr "No, a normal person would pull the drain plug! Please go to bed No. 39
We will start further investigations on you."
