Where in the World is Carmen Sandiego?, PBS
IMDb; official game site; TV.com; TV Tropes; Wikipedia

A game show for kids, supposed to teach geography and stuff. It was based on a computer game (which I used to play when I was in high school). Um... basically, contestants would try to "catch" a criminal named Carmen Sandiego, who supposedly stole landmarks, or whatever. The show was hosted by Greg Lee, who played a "special agent" in charge of "training new recruits" (the contestants) to the ACME Detective Agency. "The Chief" was played by Lynne Thigpen (who I must have seen in some other stuff). There was also an a capella band called Rockapella, who I thought were pretty cool. They sang the theme song, as well as other stuff throughout the episodes. (I'll always remember the end of the episodes where everyone would shout "Do it, Rockapella!" just before they start singing the theme.) But there's nothing else I can really say. I don't remember the show well, and I'm not sure how much of it I watched. But it was fairly cool. There was also a spin-off called "Where in Time is Carmen Sandiego," but I don't think I ever saw any of that. And there was an animated series (not at all a game show) called "Where on Earth is Carmen Sandiego?", but I don't recall if I ever saw that. I'd probably like to....
