For me, the show gave me the most memories was "Where in the World is Carmen Sandiego?" This show (and just about everything that came up from it) was the obsession of my sister and I when we were in elementary school. It mostly revolved around children trying to capture a super thief and her agents, who were known to steal things that were borderliine impossible to steal and then leave the country. While the silly skits and the fact that a thief could steal a whole island were interesting aspects of the show, it used to drive us insane that Carmen constantly kept getting away.
Other honorable mentions would have to be Jeopardy (you'll be surprised what you can learn), Nick Arcade (a game show that involves video games), and Family Double Dare.
So, how about you?
P.S. Sorry I had to fix one of the sentences.
