Keep Circulating the Tapes: In the 2000s, the first 26 episodes were redubbed in Singapore because it was too expensive to keep paying royalties to the celebrity voices. These are the versions available on DVD, qubo, and BYUtv. Because TV reruns and DVDs of the series are nothing more than the Singapore dubbed versions, the original PBS versions are easier to find on either official VHS releases by PBS Home Video and later Chik-Fil-A or tape recordings of the old airings. Strangely enough, the official KidMango/YouTube versions of season 1 have the original voices (although "Loyalty" was never uploaded). Season 2 is harder to find, because the VHS tapes were only available to schools, libraries, churches and other institutions, and fewer and fewer of these still have VHS. (Season 3 was never redubbed, because the voices were done in Vancouver, not Hollywood, so there's no celebrity VAs to pay royalties to.)
Network to the Rescue: The show was saved by Bruce D. Johnson and backed through his startup production company, PorchLight Entertainment, because he loved the original book.
The Other Darrin: Everybody is entirely recast in season three after the series returned from its two-year hiatus, with the voices being done in Vancouver instead of Hollywood. For example, in the first two seasons, Zach was voiced by PamelaAdlon, but in the third season, he was voiced by AndrewFrancis.
Also, in the 2000s the first two seasons were redubbed in Singapore (because it was too expensive to keep paying royalties to the celebrities), giving us whole new set of Other Darrins.
Recursive Adaptation: The series has spawned several paperback picture books when it first aired... while being based on a moral-focused anthology.
Similarly Named Works: Most of the episodes in the third and fourth seasons have the same titles as the ones from the first two seasons.
