During a visit to the mental hospital, I asked the Director 'How do you determine whether or not a patient should be admitted to the hospital?'
'Well,' said the Director, 'we fill up a bathtub, then we give a teaspoon, a teacup and a bucket to the patient and ask him 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 drain plug. So...do you want a bed near the window?'
