This is one of the crazier things we've ever seen on TV. Back in 1956, the only living witness to the Lincoln assassination appeared on the game show I've Got A Secret. The 96-year-old Samuel J. Seymour appeared as a mystery guest on the show despite having an accident at the hotel before the taping. The contestants get to the bottom of Seymour's identity pretty quickly and he gets many well-deserved rounds of applause throughout his appearance. This was Seymour's final public appearance as he sadly passed away later that year.
