- Author Existence Failure: Dominic Lucero was diagnosed with lymphoma after the first season, appeared in the third while undergoing treatment, and died a month before the final episode was filmed. That last episode was made in his honor.note
- Choreographed By Cast Member: Several episodes were choreographed by Ivan Dudynsky. His dance bumpers tended to be some of the more memorable.
- Hide Your Pregnancy: Averted; Julene Renee was noticeably pregnant during the last few episodes, and gave birth to her baby just after the final episode was finished.
- Subverted with Lisa Vale, who left the show for maternity leave during season 3, to be replaced with Amy Ehrlich and Jennifer Cihi.
- In Memoriam: The season 1 episode "First Date" included a tribute to Toto drummer Jeff Porcaro (who both Benny Hester and series guitarist Marty Walsh knew for several years from Porcaro's work as a session drummer) following Porcaro's death on August 5, 1992note .
"This one's for our friend Dominic, who couldn't be here."
- Though it wasn't listed in the credits, there was a dedication to Dominic Lucero near the end of the final episode:
- Keep Circulating the Tapes: As of now, a DVD release seems unlikely outside of the unofficial one on iOffer. However, the entire first and fourth seasons have been uploaded to YouTube by various people, as well as episodes from seasons 2 and 3, and they're all pretty easy to find there.
- Kudos to drumstix555 for uploading almost the entire show to YouTube in near-pristine quality. Unfortunately for us, he has one tape that's damaged beyond repair, and it contained a good chunk of Season 3 and a few missing episodes of Season 2. (Some of those season 3 episodes have been previously uploaded by other users, in multiple partsnote .) Another user has the first date episode (which isn't on drumstix555's channel) in perfect quality. Even more notably, it's from the episode's first airing on SNICK in 1992 (complete with Eye Catch bumpers).
- The first two episodes were also released on VHS, as part of two SNICK compilations.
- Amazingly, on October 10, 2015, TeenNick's "The Splat" block aired the first two episodes of the show — the first time that any episode of the show had been shown on TV since Nickelodeon's 20th anniversary celebration in 1999.
- No Budget: Cardboard props and so forth. There's a good chance that the producers were going for Stylistic Suck, giving it a "bunch of friends putting on a show in their trainyard" feel. However, the show was Nickelodeon's most expensive to produce at the time, because of the complexity and specialization of the props, even if they were made of cardboard. Most of them, cardboard televisions aside, couldn't be used for more than one episode, as props were typically specific to an episode. Occasionally, things like a hat with socks on it for dog ears will pop up in multiple episodes (the Abusement Park and School Play episodes, for example), but most of the time, props were too specific to use more than once.
- Reality Subtext: The season 2 premiere was Lisa Vale's first episode. The plot revolved around her character trying to fit in with the other, more popular people.
- Screwed by the Network: Not exactly, but Nickelodeon pretty much hated the show. Roundhouse's writers narrowly avoided getting screwed in the early seasons, with Nickelodeon supposedly preferring certain cast members over others and getting sketches cut that the writers wanted kept in. (They ended up moving production out to California starting with season 2 to apparently avoid more of this. Still got screwed in the end.) However, the show did get a promotional boost from Nick in at least its first few seasons, and the cast even took part in two consecutive editions of their annual Nick Takes Over Your School sweepstakes.
- Twofer Token Minority: Cast member Micki Duran is of Hispanic, African American and Choctaw descent.
- What Could Have Been: According to the Easychair Expressway fansite, the Honda Accordion bit from the Grand Finale was originally written for the divorce episode, in season 2.
- Written by Cast Member: John Crane, who usually plays Dad, was part of the Roundhouse writing staff and wrote several skits and songs for the show.
