Gyro, tired of being looked upon as a "gadget man", invents a time machine and uses it to go back in time to the Middle Ages.
This episode contains examples of the following tropes:
- Alcohol Hic: The drunken dragon does it.
- An Aesop: Focus on your own strengths and achievements rather than those of others, which will only bring unhappiness.
- Berserk Button: Being called 'gadget man' becomes this for Gyro for awhile after he gets so thoroughly sick of Duckburg's residents' over-reliance on him for his mechanical skills.
- Black Knight: Lestred's lackey. Parodied in that he turns out to be a skinny egret with a high squeaky voice inside the armor.
- Distracted by the Sexy: Gyro momentarily forgets how stressed and out-of-sorts he is when a beautiful egret girl asks him to fix her toaster...only to go right back to his bad mood when he makes it worse and she calls him a 'gadget man'.
- Easily Forgiven: In the end, Gyro has no grudge against the egret girl for her temper in the beginning. Of course, he wasn't angry at her specifically.
- The Good King: Arty.
- Green-Eyed Monster: Merloon is envious of Gyro.
- Horrible Judge of Character: Merloon learns this the hard way when he helps Lestred out to try and oust Gyro, never imagining that Lestred would rather use the opportunity to instead take over the entire kingdom rather than just eliminate one knight.
- Implied Death Threat: One of Gearloose's customers (the one in a Bankruptcy Barrel) threats him with a "long travel with no way back" if he don't fix his dressing machine soon.
- My God, What Have I Done?: Merloon's reaction after his temporary alliance with Lestred."So, the double-crosser has been double-crossed."
- Nerd in Evil's Helmet: The ever-menacing Black Knight turns out to be a squeaky-voiced egret wearing a massive suit of armor.
- Projectile Toast: Gyro tries to fix a toaster that's so off-whack it's shooting the toast through the ceiling. He goofs it up and ends up causing the toaster to break through the table and hit the floor.
- Rewarded as a Traitor Deserves: After betraying King Arty to Lestred, the latter sends Merloon to the dungeons.
- Royals Who Actually Do Something: King Arty managed to temporarily hold off Lestred's invasion.
- Whole-Plot Reference/Shout-Out: Merloon getting jealous of the time-traveling Gyro and temporarily teaming up with Lestred to try and get rid of him is highly reminiscent of Merlin's role in A Connecticut Yankee in King Arthur's Court.
