• Hey, It's That Voice!: Dana Snyder, the voice of The Alchemist, is also the voice of Master Shake on Aqua Teen Hunger Force which he also created.
    • The creators mentioned (when on a panel for a Dragon Con) that they asked Snyder to sound more like Master Shake when voicing the Alchemist than he had originally done.

Doc Hammer: "That was Batman. Batman's readin' crap that we wrote."
Jackson Publick: "Yeah... don't be afraid to sound more like Batman!"

  • One of Us: In the commentary for "The Diving Bell vs. the Butterglider", Doc Hammer and Jackson Publick mention several trope names before specifically stating that they read TV Tropes.
  • Shrug of God: After an episode was made that strongly implied if not stated outright who the boys' mother was, the creators said that they're still not sure themselves whether or not she is, as they don't plan too far ahead with episodes and it just sort of happened.
  • Talking to Himself: Every comedy duo in the show except for the Venture boys themselves (Monarch and Dr. Girlfriend, 21 and 24, the Murderous Moppets, Billy and White, Watch and Ward, Doe and Cardholder) are voiced by writers Doc Hammer and Jackson Publick; Publick also voices Hank, Sergeant Hatred, Action Man, Col. Gentleman, Ned, the Pirate, and Dr. Henry Killinger. He talks to himself a lot as a result. Doc Hammer does it the most often between Dr. Girlfriend and 21, while James Urbaniak gets in on the act with all Dr. Venture/Jonas, Jr. conversations. The season four episode "The Revenge Society" has Urbaniak in a three-way conversation with himself, but the writers try to keep the number of Talking to Himself instances down. For example, any time 21 and 24 interact with the Venture twins, 21 always pairs up with Hank so that Jackson Publick doesn't play both sides of the conversation; similarly, most of these characters are often kept inside their Cast Herds so that they do not interact with the voices most similar to their own (the Action Man has yet to talk to Sgt. Hatred, for instance, while 21 and Billy are always kept far away from each other).
  • What Could Have Been: Listening to the creator commentary on some episodes is kind of sad once you hear how many interesting tidbits had to be cut for time:
    • The Freudian dream sequence in "The Doctor is Sin" had a fairly interesting backstory that had to be cut.
    • "Doctor Quymn, Medicine Woman" was slated to have a flashback implying that Dr. Quymn could be the boys' biological mother (hence why she resembles Dean so much) as well as some Pet the Dog moments for Dr. Venture.
    • A deleted scene on the season four vol disc would have shown Dr Killinger showing up to help The Revenge Society recapture some of that sweet, sweet evilness.
