There's also "Jackie Rogers, Jr.'s $100,000 Jackpot Wad", a sketch performed on SNL in the 1984-85 season. The game according to "Jackie" (Martin Short) was "...like Pyramid, only different." Check out the "chocolate babies" moment. That was a moment inspired by someone that knows the show.
Additionally, I remember an in-house video segment produced by ABC News on the topic of inflation. The video, titled "The $70,000 Pyramid" was taped on the Pyramid set at the old Elysee Theater. I think Peter Jennings or Ted Koppel moderated the piece.
