Who is Normal person?

A journalist goes to a Mental Hospital to interview the doctor there.
.
He asks the doctor: How do you determine whether to admit a mental patient or not?

Doctor: 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 it's bigger.

Doctor: No, a normal person would pull the drain plug! Please go to bed No.39. We will start further investigations on you!
