When Craig Richards enters the office where O'Mally, Carl and Benson were snooping at papers, he walks over to a desk and pulls out the drawer and removes a gold watch. We see him grab a pretend drawer and pull his hand back and we hear the sound of a drawer opening but there is no drawer, he then picks up the gold watch from the chair and puts it on his wrist.
When Carl the Gnome is in the chiefs office trying to get him to over look any possible indiscretions which may come along in the next couple of days, when the chief says "Fine" and gets up and walks away the microphone is visible for a couple of seconds above Carl's head.
