During a visit to a mental asylum, a visitor asked the Director how they decided 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. So do you want a bed by the wall or near the window?"
