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