Waaaaaakkkk!!!! Clarence "Ducky" Nash, the original voice of Donald Duck, appeared as an imposter on To Tell The Truth in October 1963. Gene Rayburn (Match Game, ex-Choose Up Sides) was filling in for Bud Collyer. Panelists Orson Bean & Tom Poston would have that chore the following two weeks.
Nash appears in game 2, but didn't get a single vote from Bean, Poston, Sheila MacRae, & Kitty Carlisle.
Bean & Rayburn would switch places the following week, and the panel would correctly identify two more challengers.
There is at least one episode of Choose Up Sides now available on YouTube. We'd previously posted a standard intro, so maybe we'll get a full show up soon.
