During a visit to the mental asylum, a visitor asked the Director what the criteria was, which defined whether or not a patient should be institutionalized.
“Well,” said the Director, well prepared for such questions as these. “What we do is fill up a bathtub with water, 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,” said the visitor. “A normal person would use the bucket because it’s bigger than the spoon or the teacup.”
“Actually no,” said the Director. “A normal person would pull the plug to let the water out of the bathtub. Do you want a bed near the window?”
