 CONT: Columbo pays an office visit to Dr. Moss, who is Beau  Williamsons cardiologist. To add to the comedy of the scene, the  doctor insists on examining Columbo as he answers his questions. As  Columbo is leaving the examining room, we see his suit jacket and  raincoat folded over his right arm. In the next shot, as Columbo  emerges through the door into the waiting room, his jacket and  raincoat have suddenly shifted sides, and are now folded over his  left arm.
