A doctor was taking a group of interns on rounds at a hospital. All of a
sudden, another intern came racing down the corridor, shouting "Quick, doc-
tor, give me a pen!" The doctor reached into his pocket and handed the intern
something. The intern looked at the object and said, "Doctor, this isn't a
pen. It's a rectal thermometer." The doctor looked at the thermometer and
exclaimed, "Dammit, some asshole has my pen!"
