Well, audibly, by Bill's week of episodes, they began using the time's up schoolbell that sounded similar to Child's Play, another former Goodson/Todman culture hit that Bill himself calls it. Now, MG-HS Hour wasn't the first NBC show to establish a 5-episode limit, Hitman had a 10-episode limit, Just Men had women players shown the exit after winning 5 episodes if the car didn't start or if her key selection started the car. Looking over with the episode guide, surprised that Martha Smith appeared on this show but not her older sister Shelley, who starred on her own series "For Love and Honor".
