Eleanor Roosevelt on "What's My Line?" game show (1953)

On October 18, 1953, former First Lady Eleanor Roosevelt signed in as the "mystery challenger" on the popular game show What's My Line? By allowing the show's host to answer her initial questions, she managed to stump the blindfolded panelists for a while. But, after a few rounds, the 69-year-old Ms. Roosevelt started answering the questions herself and that's when one of the panelists got wise to her identity.
