Phineas and Ferb have decided to construct the world's tallest building. In true [[ArtisticLicensePhysics fashion]], the boys build all the way to the Moon. Meanwhile, (still in the A-Plot) Candace is frustrated with attempts to bust her brothers, but Albert Du Bois (Irvin's older brother) develops a crush on her and offers to help. Simulataneously, Doof [[ArtisticLicenseAstronomy wants to turn the Moon around]], and Perry goes to foil him.

* ComicallyMissingThePoint: When Dr. Doofenshmirtz realizes the flaw in his plot.
-->'''Doofenshmirtz:''' ''Dummkopf!'' I should have rotated the ''sun!''
* ContinuityNod: Both the spacesuit as well as Isabella's own from [[{{Recap/PhineasAndFerbOutToLaunch}} "'Out To Launch'"]] appear.
* EvilVersusEvil: Doof wants to turn the Moon around to prevent full moons from forming because his evil remains the same while general evil increases during that period and he doesn't like the competition.
* EvilWillFail: Regardless of Doof turning the Moon around or not, full moons will take place.
* ExactWords[=/=]TemptingFate: Albert insists "no force on Earth" could get rid of the giant skyscraper before Linda gets home. Instead, it disappears because of Doofenshmirtz turning the Moon around.

* RecurringExtra: Making his third appearance, Albert officially achieves this.
* TemptingFate: Albert claims the building will never disappear - guess he was wrong, after all.
* TruthInTelevision: [[http://phineasandferb.wikia.com/wiki/The_Doof_Side_of_the_Moon Crime actually does increase during the Full Moon.]]
