Executive Meddling: Gene was distinctly told not to goof around as he did on Match Game, despite a goofy host being totally acceptable in a stunt-based show. He was also not given much of a pre-show briefing, as he stumbles around aimlessly more than a few times in the Prize Vault. Considering that the Prize Vault was timed (using the seconds the couple had earned in the front game), this was never a good thing when it happened.
The Prize Vault issue was partly fixed through stopping the clock when Rayburn needed to describe the chosen stunt; this change also helped the couples finish more stunts, winning more prizes and Bank Cards along with an increased chance of going to the Number Jumbler.
Keep Circulating the Tapes: Rayburn's tenure has never been rerun, partly because he wanted it as such. 20 of about 65 of the episodes he hosted exist among collectors. Some of Farago's episodes were rerun by CBN in late 1986.
Missing Episode: Minus a week of reruns in December 1985 (the first week of the series), no Rayburn episodes have been reran. The most common explanation is because Gene was extremely dissatisfied with Bank and refused to talk about his experiences on it during interviews near the end of his life. As a result, you likely won't be seeing Rayburn's tenure again outside of YouTube.
