In the Scooby-Doo and Guess Who? episode "Total Jeopardy!" (released this past Friday to honor Alex Trebek) Velma and Shaggy compete against a robot. The episode mentions that it was the first time ever a robot had competed on Jeopardy. In real life, there was a three-part episode of Jeopardy called "The IBM Challenge," in which a robot named Watson competed against two humans for the first time ever. It is very likely that the plot of the Guess Who episode was inspired by this episode of Jeopardy. The three-part episode aired over the span of February 14-16, 2011.
