Nerdy Dancin'

Have you seen the fancy dancing on the show? I can fake it in the school auditorium, just not in a nationally syndicated dance show.

Candace signs up Jeremy to be her dancing partner on a hit dance show. Jeremy seeks out help from Phineas and Ferb because he is worried about his lack of dancing skills, and Ferb's excellent dancing skills are put to use. Meanwhile, Doofenshmirtz and his league of evil scientists seek to get their message out at the dance studio.

Episode Summary
Jeremy joins Candace and Stacy in time to watch their totally favorite TV show because Candace wanted to show him something "Impossibly important". Candace and Stacy get exicted when Let's All Dance Until We're Sick comes on and announces that it is coming to Danville. It is then that Candace reveals she already entered Jeremy and herself. Jeremy excuses himself to get some air, and the girls think he is excited. In truth, Jeremy is nervous about dancing in a show and confides in Phineas and Ferb who were wondering what they were going to do today. Phineas suggests that Ferb could teach him some moves, but after a demonstration, Jeremy decides there would be no way he could learn that dance by tonight. Phineas knows what he and Ferb are going to do today and Jeremy will not have to learn any new dance moves.

At this point, Perry is receiving his briefing from Major Monogram. It seems Dr. Doofenshmirtz has been buying the entire Tri-State Area's supply of potatoes, bacon, and chopped green onions; a recipe for evil, literally. Perry leaves headquarters to investigate.

In the backyard, Phineas unveils his and Ferb's newest invention, the Ferbalistic Groovatron 9000. It is an exoskeleton that will mimic Ferb‘s moves while he wears a special suit. Jeremy is to put it on under his clothes and nobody will see it helping him with dance moves.

Perry flies to the Doofenshmirtz Evil Incorporated building and is taken in by a large robotic arm. He is captured on a platform with his arms and legs shackled spread-eagle, discovering Doofenshmirtz and Norm are preparing for a potluck and press conference. Doofenshmirtz decides to leave Perry trapped on a platform to meet his doom. As Doofenshmirtz leaves to the meeting on Norm, a laser is slowly firing its way up to split Perry in half, an idea Doofenshmirtz got from a movie. When the two are gone, Perry easily slides out of his shackles and follows them.

Meanwhile, Candace is sure she and Jeremy are going to win while Jeremy watches her nervously. The two go onto the dance floor where Nikki Stars explains the rules and the dancing begins. Phineas and Ferb are backstage, ready to help Jeremy when it is needed.

At the meeting, the evil scientists await with no press present. Doofenshmirtz tells them to be patient and besides, when has he ever let them down? "Far too often" Rodney, or as he likes to be called, Aloyse Everheart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein, replies. Doofenshmirtz blows him off and tells them why they're here, to reveal the existence of the League Of Villainous Evildoers Maniacally United For Frightening Investments in Naughtiness. In other words, Lovemuffin. Rodney says it won't be possible if there aren't any press of any kind around. Doofenshmirtz attempts to assure them they will be arriving, but Dr. Diminuitive doesn't think so, as they are all covering the Let's All Dance Until We're Sick contest. Dr. Doofenshmirtz decides that if the press won't come for them, then they will got to the press. Immediately, all of the evildoers leave to the dance show, just as Perry arrives to the conference. After a brief look around, he takes off to follow them.

The scientists barge in on the contest and try to get the press's attention to no avail. Doofenshmirtz wonders why and Rodney tells him it's a dance show, the cameras only stay on the best dancers. All the scientists start dancing to get their message of evil out, but all of them, including Rodney and Doofenshmirtz are horrible. Perry arrives and gets a message from Major Monogram. He has to stop all the evil scientists so their message won't go out and so they won't ruin what has become his and Carl's favorite show.

Jeremy and Candace, meanwhile, are doing well at the start of the competition. Once the contestants start getting eliminated, Candace suggests they kick it up a notch. Jeremy looks over at Ferb who gives him a thumbs up and begins to dance backstage, helping Jeremy with both solo moves and when he was partnered with Candace. Doofenshmirtz is dancing not far from them, attempting to talk into a camera but is eliminated, as is Rodney. The two begin pushing other dancers away to take their places but are eliminated time and time again. Perry helps the judges by semi-violently eliminating the other scientist contestants.

Stacy, in the audience, cheers for the Jeremy and Candace and throws a bouquet out to them. A bee flies out of it and heads backstage, circling Ferb as he swats at it. Jeremy becomes a fan favorite when the swatting makes it look like an impressive dance move. Because Doofenshmirtz and Rodney are knocking out dancers, Perry eliminating the scientists (including Doofenshmirtz and Rodney), and the judges eliminating dancers, only Jeremy is left on the stage. Ferb has him finish off with an impressive dance move and ending with a split.

The host is so impressed by his moves that she invites him to dance on the show every week. Candace tells Jeremy to do it, as they will be dancing stars, but Jeremy confesses his help and reveals the exoskeleton. Candace, the audience, and the judges gasp. Jeremy pulls the curtains back and reveals Ferb, who declares his work is done, and dances up a pole, earning a perfect score from the judges. Jeremy apologizes to Candace, but she that she doesn't mind that Jeremy can't dance and just wanted to have fun and dance until they were sick. Jeremy admits he is feeling a little dizzy and Candace escorts him out of the studio, reaffirming their mutual attraction to each other.

Finally, the scientists are all seen in the intensive care unit after Perry's mission is successful, causing Dr. Doofenshmirtz say, "They should have called it 'Let's All Dance Until We're in Intensive Care' ".

 * The music played during Ferb's dance is the instrumental version of the Spa Day song.
 * Candace doesn't interact with Phineas and Ferb in this episode.

Errors

 * When Ferb first demonstrates the Dance-o-tron he spins, but Jeremy does not; since he's supposed to mimic Ferb's moves when using the Dance-o-tron exoskeleton. (No device is readily visible to indicate how Ferb is being selective in transmitting motion commands to Jeremy's exoskeleton.)
 * The overall size of Jeremy's body changes rapidly when he and Phineas help Ferb up out of his split.
 * The first woman eliminated was eliminated again, the second time swinging her arms and bouncing her legs.

Also when Ferb leaves the studio with his moon walk move, the judges give his move a 10, there the look-alike cartoon sheds a tear, which kinds of tells that Dan is proud of the show.
 * During the coverage of Let's All Dance Until We're Sick in Danville, the boy who raises rats from Mix and Mingle Machine can be seen in the background holding a sign.
 * When the on-stage audience starts copying Jeremy, and Nikki Starrs is talking, the on top of cool lady can be seen.
 * When Doofenshmirtz says "Wow, cutting deep, man," he is most likely referring to how much Norm's vocabulary has changed since "Greece Lightning".
