During a visit to a psychiatric clinic, a journalist asks the Director about the criteria used to determine whether a patient should remain at the hospital or go home.
"Well," says the Director, "We do the following test: we fill a bathtub, then offer the patient a teaspoon, a cup and a bucket and ask him to empty the bathtub. Depending on how he empties the bathtub, we know if the person should remain interned and how to proceed with treatment.'
"Ah," says the journalist, "A normal person would use the bucket because it's bigger than the spoon and the cup".
"No," says the Director. "A normal person would just unplug the bathtub... Would you prefer a room with or without a view of the garden?"
