Bathtub test

During a visit to the mental hospital, I asked the Director how do you determine whether or not a patient should be institutionalized? 'Well,' said the Director, 'we fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub.' 'Oh, I understand,' I said. 'A normal person would use the bucket because it's bigger than the spoon or the teacup.' 'No' said the Director, 'A normal person would pull the plug. Do you want a bed near the window?'
