When everyone is at the murder board discussing who could have killed Sazz, Christmas Guy is suspected but Charles says he was out of town. Mable disagrees and points out they found a piece of what looks like tinsel and a close up shows her holding the tinsel in her hand and then letting go while talking. The camera switches to a full screen shot where Mable is finishing her sentence, but is still holding the tinsel.
In this episode they monitor and listen to a ham radio. At the end of the episode Mabel gets on and talks to a user on the radio using a made up code name. In order to talk on a ham radio you must study and take an entry exam to become a technician at the introductory level and use a series of letters and numbers given to you by the FCC. Using code names is used more on CB which isn't monitored as heavily by FCC and is open to general public.
