** VictoryIsBoring: Of course, he eventually reaches an epiphany, realising that despite his success, he has found no happiness.

* WritersCannotDoMath: Cosinus equal to 17 is by definition an impossible result.

* AbsenteeActor: Stacy, Jeremy and Irving do not appear in the episode; the Fireside Girls only appear in the last song. This was because the creators wanted this episode to focus more on the main characters and not the supporting characters.

* WritersCantDoMath: Cosinus equal to 17 is by definition an impossible result.

* NoFourthWall: The song "Thank You For Comin' Along" breaks the fourth wall in various ways. The characters acknowledge events that occurred in the series that they normally would not know about, such as the events of "[[AllJustADream Phineas and Ferb Get Busted]]", "[[LaserGuidedAmnesia Across the Second Dimension]]" and "[[FlashForward Act Your Age]]". The song also has the characters singing to the audience, thanking them for watching. At the end of the song, Phineas waves goodbye to the audience before closing the door. During the song, Phineas also mentions that "Unfair Science Fair" has "two parts".

* ThrowTheDogABone: Doofenshmirtz finally gets one over on his brother, takes over the Tri-State area, reconciles with Vanessa during the time loops, and even thinks he saved the day (it was really Candence since the -inator to fix the loops wasn't plugged in but Perry never reveals this to him).
