Keep Circulating the Tapes: Cartoon Network pulled the show after its first run and never bothered to rerun it. In an even bigger disappointment to fans, they also never bothered to release any of the series on DVD, so, up until October 2012, unless you were comfortable with watching the show through methods of questionable legality or iTunes, you were pretty much completely out of luck. Thank God it's being re-aired on Toonami, which may or may not herald a forthcoming DVD release.
The Other Darrin: Kimmy is voiced by Cassie Scerbo in her first appearance in "Showdown at Sherman High." Both her and Kari Wahlgren, interestingly enough, voice characters in Randy Cunningham: 9th Grade Ninja. Young Lance is also voiced by different child actors in "Shaman of Fear" and "Shadows of Youth," although it could be that he's at a different age.
Screwed by the Network: Getting moved from Friday nights to Wednesday nights then finally moved practically unannounced to an early Saturday morning slot all in the first season alone is never a good sign.
