A visitor to a mental institution asked the director how he decided which patients should be kept in. The director said:"We fill up a bath, then offer the patient a teaspoon, teacup or a bucket & ask them to empty the bathtub." The visitor said:" Oh, i see, a normal person would choose the bucket, because it's biggest" The director said "No, a normal person would pull the plug out. Would you like a bed near the window?"
