During a visit to a mental asylum, a visitor asked the Director what the criteria is that defines if 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 the patient to empty the bathtub.”
“Oh, I understand,” said the visitor. “A normal person would choose the bucket, as it is larger than the spoon.”
“No,” answered the Director. “A normal person would pull the plug. Would you like the bed by the window?”
