Thanks for clarifying that about Double Dare 2000, Adam. I believe that last episode of DD2K aired on September 10, 2000. I could be wrong, though (that date came from a source I can't remember).
Also, just to clarify that information about Family Double Dare, there were 13 episodes of the Fox version and the number of episodes for the Nick version is very close to what Jason originally said (82 episodes).
