Phineas and Ferb create trampolines in the sky thanks to an antigravity device, which gives Candace problems during a brunch with Jeremy's family. Meanwhile, Doof builds a Tell the Truth-inator to force the people of the Tri-State Area to blab their deepest secrets.
Tropes:
- Answer Cut: When Candace gets hit with the antigravity device, she says "There's gotta be a reverse switch!". The scene then cuts to Phineas and Ferb at the hardware store, asking the store owner where to find the reverse switches.Mr. Haney: Right behind ya, next to that guy buying self-destruct buttons.
Doofenshmirtz: Ah, sweet! 50% off with coupon! - Bait-and-Switch: When Candace gets hit by the anti-gravity device, it appears to set up that she is the one who will be hit by the Tell-the-Truth-inator. But just as she is about to spill the beans, the Inator hits Suzy instead.
- Call-Back: When Doofenshmirtz fires the Tell the Truth-inator at a woman with a mirror, the beam gets reflected back at Doofenshmirtz, who says "Secretly, I'm very lonely", which was spoken by Bobbi Fabulous in "Dude, We're Getting The Band Back Together!" and Norm in "Greece Lightning".
- The Cameo: Blay'n and Clewn't, the Christmas elves from "Christmas Vacation" appear briefly during the song.
- Cannot Tell a Lie: The purpose of the Tell the Truth-inator.
- Dude, Not Funny!: When Doof is being chased by the Abe Lincoln robot, he tells Perry that it's about to "John Wilkes my Booth!... What? Too soon?"
- Fun with Acronyms: Monogram tells Perry that Doofenshmirtz was spotted with a grocery list reading "Eggs, Vitamins, Ice, and Leeks", which seems innocuous until one notices that the letters spell "EVIL".
- Karma Houdini Warranty: Suzy gets caught for ruining Candace's life for the first time, thanks to the Tell the Truth-inator.
- Magic Skirt: Lampshaded by Linda when Candace floats and her skirt does not flip downward.Linda: Good thing she's wearing her skort.
- Mirrors Reflect Everything: Doof points his inator at a (offscreen) woman holding an "unusually large hand mirror". The ray of the inator bounces back to him causing him to admit, "Secretly, I'm very lonely."
- Sand In My Eyes: Buford tears up when seeing Phineas bounce on the floating trampolines. But he then moves his tear to Baljeet to cover up.
- Shmuck Bait: Doofenshmirtz leaves a recorded message for Perry telling him to try some food and to not try and destroy his new Inator. When Perry does just that, he gets his legs caught in a trap.
- Shout-Out:
- At the end of the song, Doof dresses like Marty McFly from the prom scene in Back to the Future.
- When Robot Abe Lincoln tries to smash Doofenshmirtz with his fist, he yells "Honest Abe Lincoln Smash!", a nod to The Incredible Hulk.
- Slow "NO!": When Suzy throws Candace's rare Ducky Momo plate, Candace does this.
- Turned Against Their Masters: The Tell-the-Truth-Inator features a robot version of Abraham Lincoln who's meant for decoration. When the robot gets hit on the head by a fast baseball, the robot comes to life and starts fighting against Doofenshmirtz.
- What Happened to the Mouse?: Sure Antigravity Maximus and the trampolines are gone, but whatever became of the personal antigravity remote Ferb used in the beginning?
