I got three answers!
1). Henry Beckman; played a security guard on Don Adams sitcom, Check It Out, appeared on Scrabble (80's).
2). Lonnie Burr; Mickey Mouse Club mouseketeer appeared on WordPlay. He won over $1,000. On the second show, the celebrities wore mouse ears in his honor. When he was defeated by the female contestant, the celebrities sang the closing theme of Mickey Mouse Club!
3). Emile Sitka; Three Stooges supporting player who was the only supporting star to work with ALL the Stooges (Moe, Larry, Curly, Shemp, Joe & Curly Joe; Half-Wits Holiday was his first short as well as Curly's last) appeared on Let's Make A Deal (1984-86). He dressed as Uncle Sam & Monty made a quick deal of $500 or the curtain. Emile took the $500 & avoid being zonked! If he had been zonked, he might've poked Monty in the eyes (LOL)!
