Trivia: Dexter's Laboratory

  • Actor Allusion:
    • Koosie making a pepé wrap is an allusion to Dom De Luise's second career as a cook.
    • Rasslor from the Dial M For Monkey episode of the same name was voiced by Randy Savage. His last line in the episode was, naturally, "OH YEAAAH!".
    • "Just An Old Fashioned Lab Song" is wall-to-wall references to guess star Paul Williams' music and personal life. note 
  • Adam Westing: Koosalagoopagoop is voiced by Dom De Luise and is a parody of the increasingly saccharine Don Bluth movies DeLuise had been in, like A Troll in Central Park.
  • Adored by the Network: Well not surprising considering it was one of Cartoon Network's first successful original animated series. But from 98-2001, it, along with Powerpuff Girls were the flagship shows of the network.
  • Cross-Dressing Voices: Dexter was voiced by two women in English. In Mexican Spanish, German, Danish and Portuguese dubs Dexter is voiced by a man.
  • The Danza:
    • Paul Williams himself guest stars in the episode "Just an Old Fashioned Lab Song" as Dexter's piano instructor.... Prof. Williams, who is drawn roughly the same height as Dexter.
    • The foreign exchange in "Last But Not Beast" is named Toshi and voiced by Brian Toshi.
  • Hey, It's That Voice!: Dexter's first voice was Chuckie Finster, Babe, and Gosalyn Mallard (Christine Cavanaugh); his second voice was Sweetie Bird, Coco, Ann Gora, Lonette, and that loud, obnoxious teacher (and the mom) from Cow and Chicken (Candi Milo).
  • Keep Circulating the Tapes: Bits of the first season were released on a now out-of-print VHS tape, the same goes for a collection of Genndy's favorite episodes. "Ego Trip" was released only on VHS, and that's out of print as well. The first season did get an official DVD release, but it does not include the banned "Dial M for Monkey" cartoon "Barbequor". Thankfully, the entire series (sans "Barbequor" and "Dexter's Rude Removal") is available on iTunes, and the entire first and second seasons (again barring "Barbequor") are available on Netflix.
    • "Barbequor" is available on Netflix in the UK.
      • As of May 3rd 2015 all Episodes (Minus Barbequor) are on Hulu.
    • Rude Removal became this after it was finally shown to the public. [adult swim] got its hands on the episode and actually aired it, and afterwards posted it on their YouTube. Shortly thereafter, the episode was made private and there currently doesn't exist any official release of it.
  • Missing Episode:
  • Official Fan-Submitted Content: The script for "Dexter and Computress Get Mandark!", if you couldn't tell already.
  • The Other Darrin:
    • Dexter's VA went from Christine Cavanaugh to Candi Milo when the former retired from voice acting early on in the last two seasons.
    • Dee Dee's VA continuously alternated between Allison Moore and Kat Cressida.
  • Shrug of God: Even the series creator Genndy Tartakovsky isn't certain about what Dexter's bizarre accent is supposed to be.
  • Talking to Himself:
    • Frank Welker does this whenever both Monkey and Quackor face off.
    • Eddie Deezen voiced Mandark and his sister Lalavava.
  • Writing by the Seat of Your Pants: Genndy Tartakovsky, who was at the peak of his workaholism at the time, claims that the original show was produced so quickly that he didn't even see the finished product until it was on television.
  • Write Who You Know: Dee Dee and Dexter's relationship was based on creator Genndy Tartakovsky and his brother Alex, who was always destroying Genndy's personal projects when they were younger.
