Mr. Monk Goes to the Hospital

S5, E16: It's late at night in a major hospital, and everything is quiet. An old man shuffles down a hall, into an elevator, and right into the office of Dr. Graydon Whitcomb. With an amazing burst of strength and speed, the old man lifts his oxygen tank and swings it at Dr. Whitcomb's head! The next day Monk shows up at the hospital with his own medical emergency: a bloody nose. His seemingly incurable nosebleed leads him to seek out Dr. Whitcomb, the hospital's chief of neurotrauma. Entering Whitcomb's office, Monk bumps into a coffee table, and then into the dead body of Dr. Whitcomb!
