Episode Summary
In an attempt to organize the chores at A&A Music Factory and pass and upcoming health inspection sent by the Mall of Miami, Ally installs an upright gaming wheel in the practice room. Trish walks in and announces that she has booked Billie and Bobbie to perform at the music school in front of their students. Due to the feminine spelling of both of their names, none of the team are truly certain of which is the brother and the sister. Dez tries to help by opening his laptop and showing video footage of their act, but it doesn't work. They spend much of the episode trying to figure this out.

Bobbie and Billie's act is extremely perky and cheesy. They tend to dress like mid-1970's pop musicians, and their act consists mainly of singing their theme song and telling corny jokes. Everyone but Dez finds their act way too corny, although Ally realizes how corny they are but still accepts them. Some time before performing in front of the students, they sabotage the music factory so that they can fail their inspection, placing condiments in the wind instruments, rats in the vending machines, and too much soap cleaning up the bathroom and leaving the sink on so that bubbles run all over the school. When she and her brother end up getting ketchup and mustard on each other after using the wind instruments, they happily go to the food court to use the condiments on them for eating.

The pop-star and songwriter accuse their friends of making the mess, while they struggle to clean it up, when suddenly a health inspector named Mr. Schxlumbraugh, who's name is difficult to pronounce by all four of the team members. The inspector, demands answers about the mess, and threatens to shut the school down. As Austin & Ally are cleaning the school up, the cutesy brother and sister, and enquire about the mess. When they explain what happened, they sympathize with Austin and Ally when they hear about how Trish and Dez caused the mess in the music factory, leaving Austin and Ally to do all the work to fix everything, and insist that Austin and Ally go get lunch while they clean up. Once they leave, the brother and sister go to talk to Trish and Dez, feigning the same sympathy, saying it's a shame they have to do the work while Austin and Allie go out and have a relaxing lunch.

Trish and Dez find their friends eating in the food court, and accuse them of exploiting them, which both deny. All four argue over how much they depend on each other to keep the school running. Lily approaches the four of them as they argue, and inadvertently reveals that the Billie and Bobbie had sabotaged The A&A Music Factory by setting up all the mishaps in order to get them shut down so they can open their own music school called "The B & B Music Factory." Austin, Ally, Trish and Dez realize what happened and resume cleaning the school, but while they're doing so, the four come up with a plan to Billie and Bobbie for the frauds they are.

Later that night before the performance at Club-a-Dub-Dub, Ally and Trish approach Bobbie, and convince her that her brother thinks he's the bigger star of the show and views her as merely his backup performer, which eliminates her usual cheerful demeanor. The scene is cut to Austin and Dez doing exactly the same thing with Billie. During the performance, Billie and Bobbie lash out at each other, and inadvertently reveal which one is which. Bobbie uses their knock-knock jokes as an attempt to accuse him of insulting her dancing, and Billie interrupts the act to perform a new version of "The Happiness Song," which evolves into a round of insults between the two of them. Both stop the song to argue with one another and reveal their proposed music school, leaving the stage as the show goes on without them. After they both storm off stage, Ally is amazed they were able to sabotage their plot so easily. Surprisingly, Dez and Lily take the stage and do their own version of the "Billie and Bobbie theme song".

Inspector Schxlumbraugh comes back to the A&A Music Factory, and gives it a passing grade, but still is upset with the team for not being able to pronounce his surname. Austin requests a copy of his paperwork, to show his parents that there are some tests that he can actually pass. After he leaves, and the team celebrates their inspection, the two singing brother and sister return to apologize (at the behest of their parents), and offer them a pie. Before they leave, they ask Austin and Ally which of the two is which, the same question Team Austin asked about them.
