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 tea-spoon, a tea-cup 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 tea-cup".
"No!", said the Director. "A normal person would pull the drain plug". "Well, do you want a bed near the window?"
