There was a contestant named Gee on \"Password Plus\" in 1980 who started near the end of the show on Tuesday. His celebrity partners were Lucille Ball and Dick Martin. He won his first game with Lucy on Wednesday\'s show. When Thursday\'s show started, Allen Ludden made a reference to back problems that Gee was having. Gee won his second game but only got $200 in Alphabetics with Dick Martin. They went back to the main set, where Allen introduced a new contestant, and then they went to commercial. When the show returned, Gee was gone due to the back problems, and Allen said that Gee would be back at a later date, when he was feeling better. They introduced another new contestant and then flipped a coin to see who would have the first option. Gee did return a few weeks later, with Betty White and John Astin, and the producers let him play that Alphabetics over again.
Later that year, by the end of the Friday show of the Susan Richardson/Bowzer week, two new contestants had played to a $100 tie, which would be broken next week. (Coincidentally, the next celebs would be Lucille Ball and Dick Martin.) On Monday, Allen brought in one of Friday\'s contestants and explained that the other was unable to return due to a \"family health problem\" and that she would come back to the show as soon as she could. They introduced a new opponent for the returnee, and they started a new game from scratch. The returning player did get to keep the $100 she won on Friday, though.
Not an illness-related situation, but on a 1979 \"Hollywood Squares\" episode that\'s on the Internet, it\'s explained that the previous week\'s contestant knew da lovely Lennon Sisters, who were on the show the new week, so the producers asked him to come back at a later taping. His challenger had been in the middle of a game with him, but she started a new game with a new opponent.
Spin-off question: Aside from the above example and the situation with \"$100,000 Pyramid\" champ Keefe Ferrandini being friends with guest celeb Terry Lester and having to sit out a week, can anyone think of other examples of returning contestants having to skip a taping because they knew one of the stars personally?
