Bath tub test

During a visit to the mental asylum, I asked the Director how do you determine 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," I said. "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?"
