- Keep Circulating the Tapes: This show is one that is still waiting for its day on DVD. It also for some reason took years of asking before Warner Archive to even confirm this show was in their library. Only two home video releases of this show exist and both are out of print.
- Old Shame: Storyboard director Jim Woodring has gone on to dismiss this from his career (as well as most of his work at Ruby-Spears), calling it a "lamentable piece of shit" in interviews.
- Out of Holiday Episode: The Halloween episode aired in September and the Christmas episode aired in November for unknown reasons.
