During a visit to a mental asylum, a visitor asked the director how do you determine whether or not a patient should be institutionalized?

"Well," he said, "we fill up a bath, then offer a spoon, a teacup and a bucket to the patient and ask him or her to empty the bath."

"I understand," he replied. "A normal person would use the bucket because it's bigger than the spoon and the teacup."

"No," replied the director. "A normal person would pull the plug. Do you want a bed near the window?"
