Background Information

 * Phineas and Ferb only appear as cameos while Doofenshmirtz takes up the role as the main character in this episode.
 * Candace doesn't appear in this episode.
 * The calendar says that September the 1st is a Sunday. This suggests it takes place in 2013, as the 2013 calendar marks said date as a Sunday.

Production Information

 * The first image of this episode was featured in the promo for Disney XD's Animacation. Along with that, the TV Listings say that this episode was supposed to air on June 13, 2014, but it didn't. Those two facts combined means that Disney had that episode since, at least, June, though they hadn't aired it until November.
 * The first episode co-written and co-storyboarded by co-creator Dan Povenmire since Phineas and Ferb Summer Belongs to You!.
 * Originally set to air on June 10, 2014, but was replaced with the premiere of "Father's Day" instead.

Errors

 * Doofenshmirtz atop Perry's hoverjet.jpg Doofenshmirtz is about to get onto Perry's hoverjet, he is wearing his outfit with a green shirt and purple tie, but when he is on Perry's jet, the outfit changes to his usual black shirt.

Continuity

 * Johnny and Vanessa are broken up, as seen in the episode "Minor Monogram".
 * In "Unfair Science Fair Redux (Another Story)", Becky was among one of the people Candace called (She says they haven't seen each other since kindergarten, probably explaining her absence in this episode). Either this could be her or a different Becky.

Allusions

 * King Kong - Johnny is climbing up the school bell tower while taking Vanessa with him, similar to how King Kong climbs up the Empire State Building, taking Ann Darrow with him, making it the second time this movie is parodied after "Attack of the 50 Foot Sister".
 * 90s Sitcoms - is a parody of the 90s High School themed sitcoms.
 * The Simpsons - Principal Lang is similar to Superintedent Chalmers.
