Journalist: How do you determine whether a patient needs to be admitted to mental hospital or not?
Doctor: Well, we give the patient a bathtub completely filled with water, along with a teaspoon, a glass and a bucket. And ask him to empty the bathtub.
Journalist : Obviously, a normal person would use a bucket, because it’s bigger and hence will use less time to empty the bathtub.
Doctor: No you dumb mind, a normal person would pull the drain plug. Admit this idiot as well.
