Shout Out / Diamond and Silver's Excellent Adventure

• The name is, of course, a nod to Bill & Ted's Excellent Adventure.

• Apple Bloom quotes the following song lyrics, in order:
  • "Suckerpunch" by Five Iron Frenzy.
  • "Black and Blue" by Fats Waller.
  • "Fables of Faubus" by Charles Mingus (specifically the early, live recording—the more famous version from Mingus Ah Um has no lyrics).
  • "U Can't Touch This" by MC Hammer
  • "Twilight Time" by Havalina Rail Co..

  • The show's theme song.
  • "Tourniquet" by Evanescence
  • "Courtesy of the Red, White, and Blue" by Toby Keith.
• There are multiple references to Homestuck:
  • Any instance of "X years in the future/past, but not many".
  • Pudding Head finds a copy of Rose's Grimoire of the Zoologically Dubious.
  • Several versions of Diamond Tiara are dressed like Dave Strider.
  • The various time traveling versions of the characters express consternation at the possibility of reading memos from their past and future selves.
  • A crowbar with the ability to nullify time travel devices is mentioned.
  • At the end, some variations on "That didn't stop being a thing that happened" occur.
• There are many references to Dragon Ball:
  • Guido appears on the cover, despite never appearing in the fic.
  • Captain Briefs of the Time Patrolmen.
  • Time-Time City, a city based off of Toki-Toki City.
  • The leader of the mysterious villains is named DemiGra, the same as one of the leaked characters for Dragon Ball Xenoverse.
  • Mentions of Agents Beat, Note, Kabra, Froze, Tsumuri and Nico.
• An unnamed wheelpone appears in far future Ponyville. And reappears at the end as one of The Duchess' disguises.
• DT & SS realizing that being in the future means there's even more history to learn, then letting loose a Big "NO!", is a nod to this Time Friends comic.
• "Once upon a time, 1000 years ago in the future!" references the catchphrase of The Cybernetic Ghost of Christmas Past from the Future.
• JB is named after Jake Berenson from the Animorphs and paraphrases the opening line of the books.

• One of the villains is a blonde vampire who once was a jockey.
• Baron Zeppeli was a good guy, until he got brainwashed by a sentient, evil top hat. Silver Spoon lampshades that this plot development is "just like that movie!"
• A ponified version of the Cyber Woman With A Corn pops out of a random time portal.
• References to Primer: Twilight mentions sticking a time machine inside another time machine during her absurd metaphor. "Terger's Hexagon" is named after Abram Terger. And Duchess Emiba is named after Abe and Aaron's home business.
• The Duchess' first name, Ritogana, is a mangled reference to "Litagano Motscoud", a significant password from (the fan translation of) Cave Story.
• And she's the Duchess of Kalevala.
• She intends to overthrow Celestia and Luna, thereby becoming the Queen of "All Day and All of the Night".
• Apple Bloom shouts "Hikeeba!", a running gag from Mystery Science Theater 3000, which was itself a reference to Women of the Prehistoric Planet.
• Apple Bloom follows the Memnan Saa school of karate and performs a "Vril energy" kick—both names from B.P.R.D., though wildly out of context.
• A nod to Sweet Bro and Hella Jeff: "Twilight and Zeppeli’s kiss did not stop from getting longer."
