During a visit to a mental asylum I asked the director how they determine whether or not a patient should be institutionalised.
"Well," said the director "We fill up a bathtub with water then we offer the patient a tea-spoon, a teacup and a bucket and ask him or her to empty the bathtub."
"Oh, I understand." I said "A normal person would use the bucket because it is bigger."
"No," said the director. "A normal person would pull the plug. Do you want a bed near the window."
