Bathtub…

During a visit to the mental asylum, a visitor asked the Director what
the criterion was which defined 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,” said the visitor. “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?”
