Mel Brooks appeared as the 2000 Year Old Man to help celebrate the 2000th episode of the original "Jeopardy!" hosted by Art Fleming (February 21, 1972), in which the three highest-scoring undefeated champions at that point returned to play an abbreviated game for charities. During his pre-game appearance he recounted how the show was done 2,000 years earlier—"It wasn't this hippy-happy-dappy game you've got here … the moment you walked out of your cave—Jeopardy!" On the March 17, 2014 airing of the current "Jeopardy!" hosted by Alex Trebek, Reiner and Brooks read an entire category of clues as their characters.
