In order to receive their allowances ahead of time so they can buy a new scooter, the nephews trick Scrooge into believing it's Saturday instead of Friday, resulting in mass confusion worldwide.
This episode contains examples of the following tropes:
- An Aesop: What seems like a small, harmless lie can quickly snowball into something much worse.
- Banana Peel: The plane taxis over one as Launchpad brings it in for a landing, resulting in another crash.
- Banana Republic: The Central American-esque country run by the militant dictatorship where Scrooge's cereal factory resides in is literally called the Banana Republic.
- Brick Joke: Fenton has to borrow a dime from Scrooge so he can use a pay phone to get ahold of the Gizmoduck suit. Then, after they're out of danger, Scrooge calls to him and Fenton answers, knowing Scrooge wants the dime returned.
- Clock Tampering: The boys alter all the calendars in Scrooge's mansion to make him think it's one day later. Unfortunately, when Scrooge McDuck thinks it's Saturday, the whole world must follow suit...
- Death by Materialism: Scrooge tries to avoid having to give Fenton a dime to call the Gizmoduck suit even though it's probably the only way he and Fenton will survive the execution.
- Gaslighting: Effectively what the nephews end up doing to Scrooge, and by extension, the world.
- Get It Over With: Fenton's way of drawing his "last words" out to buy time for the Gizmosuit to arrive annoys everyone so much that Scrooge would rather prefer to be finished off rather than have him stall for another second.
- Laser-Guided Karma: The nephews' plan to buy the scooter before the sale ends winds up backfiring for them. While their ploy to get their allowances early works, due to everyone now thinking it's Saturday the sale on the scooter ends, which means even though they now have their allowances they no longer have enough to afford it!
- Moral Dissonance: Scrooge does business with the military dictator of a Banana Republic (literally called "The Banana Republic"). Though the dictator is portrayed as a villain who attempts to execute Scrooge and Fenton at one point, Scrooge having done business with him is never portrayed as a bad thing.
- Never Got to Say Goodbye: As the cannon squad is counting down, Fenton laments never getting to tell his mother or his girlfriend Gandra farewell. However, the Gizmosuit arrives Just in Time.
- Right Hand vs. Left Hand: The triplets and Launchpad are working on clearing the clouds to show it's Friday at the same time Fenton is trying to get the Gizmoduck suit to keep himself and Scrooge from being executed. The Gizmosuit goes straight into Launchpad's cloudplower, crashing it before he can clear the clouds completely.
- A confused Fenton says, "Right now I'd be happy if it was Tuesday and this was Belgium!", which refers to If It's Tuesday, This Must Be Belgium.
- Fenton also references Nathan Hale's last words and Marc Antony's "friends, Romans, countrymen" speech.
- During the confusion montage, someone asks, "Does anybody really know what day it is? Does anybody really care?" A parody of the Chicago song "Does Anybody Really Know What Time It Is?".
- Strange Minds Think Alike: Louie and the newscaster both call the eclipse an "eclair".
- Total Eclipse of the Plot: An eclipse turned out to be the proof needed by the triplets to show that they had pranked Scrooge into thinking it was Saturday so that he could give them their allowances early.
