Series creator Bob Doucette voices Mr. Fletcher and Duncan's yo-yo.
Show writer Roger Eschbacher voices Jim Kim.
Dueling Shows: With Recess, which should be pretty obvious to '90s kids due to the two shows having similar premises. Recess won this duel, as it lasted sixty-five episodes over the course of five seasons and even had four movies, whereas Detention only lasted thirteen episodes and didn't go into reruns. Not helping matters was that Disney's One Saturday Morning block was beating Kids' WB! in the ratings.
Detention is easily one of the shortest-lived shows to ever come out of Kids' WB, only lasting 13 episodes. According to Bob Doucette in an interview, the show wasn't what the network wanted even though it was one of the highest-rated shows on the block (it even rivaled Pokémon, which was basically the block's Cash-Cow Franchise); he also had a rough time with the executives at Warner Bros. as they had unhealthy relationships with Detention's staff team. The show ended up with a death slot of 11:30am in March 2000, and during August in the same year, it ended up being pushed to Kids' WB's afternoon block, where it only aired on Fridays. Although reruns lasted until August 31, 2001, the entirety of the series wasn't seen again for several years, with only three episodes being available on YouTube until 2018, when Warner Bros. officially released the complete series, as seen above.
Stunt Casting: Kids' WB wanted celebrity names attached to Orangejella and Lemonjella. Tia and Tamera Mowry, whom were starring on Sister, Sister on The WB at the time, were chosen as a result.
What Could Have Been: According to Bob Doucette, Billy West also auditioned for the voice of Gug, but Kids' WB wanted an actual Hispanic actor for the role. Doucette chose Carlos Alazraqui, remembering him from the Taco Bell commercials.
Written by Cast Member: Jim Kim's voice actor Roger Eschbacher wrote "The Man With the Golden Brain".
Word of God: Bob Doucette admits that Duncan Bubble was based on someone he knew who was deaf and claims that Duncan doesn't speak because he's supposed to represent handicapped kids without making it an obvious choice. He also claims that Kisskillya is actually well meaning despite her antagonism with the other students.
