Guest spots include
Diffrent Strokes- reporter
Small Wonder- game show host
Geoff told me that he had a hand writing some of the material for this episode. The producers and directors were usually open for ideas if the cast had suggestions... too bad that didn't make the show any better
I Dream of Jeannie- Banker
This one's pretty funny. Jeannie unknowingly hands Geoff a robbery note, and Geoff's reaction is priceless.
Petticoat Junction (as mentioned)- Jeff Powers
Geoff only had 5 guest spots as this character
Here's what he told me about the shows he did.
Treasure Hunt- His favorite show to host, because he got to ad-lib a lot. Chuck Barris tried to sabotage Treasure Hunt towards the end by making the skits more cruel and more mean spirited. Geoff thought he went too far and threatened to quit. Chuck gave in, but got even with Geoff by writing himself and others into the skits, only to hire anybody he could find to take their place, meaning Geoff had to work with someone that he didn't rehearse with.
Starcade- He loves video games, but didn't care much for the format.
The New Chain Reaction- The show had no audience, so it was difficult to make it fun. The people that were around were told they couldn't laugh at Geoff, because then the viewers would know there was no audience. The show's original host, Blake Emmons, was doing terrible, and Bob Stewart had to work around the Canadian Network's policy of "Canadian born talent only". So he had announcer Rod appear on camera at the beginning and the end of the show.
Hollywood's Talking- Jack Barry didn't like Geoff. He thought he wasn't right for the job. However, this didn't stop Dan Enright from later hiring him to host Play the Percentages.
Play the Percentages- A lot of people disliked Dan Enright, but Geoff told me he never had a problem with him, and Geoff occasionally joked with Dan on the show. Dan once played a joke on him by having his staff pass the cue cards around to all the staff members until the cue cards went from one side of the stage to the other. Dan handled the cue cards, and Geoff kept telling him to "keep the cards moving", so Dan took it literally.
Jackpot- Geoff told me he remembered the only time in the show's run they offered a 50k Jackpot, and the answer to the Super Jackpot riddle brought the audience to a revolt... and Geoff responded by hiding behind the bleachers where the contestants sat.
