In a psychiatric hospital, a journalist asks the doctor: “How do you determine whether to admit a person as a patient or not?
Dr: Well … we’d fill a bathtub with water and then give a teaspoon, a glass and a bucket to the patient 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 #39. We will soon start further investigations on you.
