Nerdy Dancin'

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
Candace convinces Jeremy to be her dancing partner when she finds out she and Stacy will be attending a local taping of Let’s All Dance Until We’re Sick, a hit TV show hosted by Nikki Stars. Unsure of his dancing skills, Jeremy enlists Phineas and Ferb’s help, who design a mechanical contraption that will allow Jeremy to mimic the moves of a truly skilled dancer, Ferb. Meanwhile, Dr. Doofenshmirtz and a conglomeration of other villains converge on the dance studio to get their evil message out to the people of the Tri-State Area.

Jeremy joins Candace and Stacy to watch the show Let's All Dance Until We're Sick. The show announces it is coming to Danville, and Candace has already signed Jeremy and herself up for it. Jeremy excuses himself to get some are, and the girls think he is excited. In truth, Jeremy is nervous and confides in. Phineas suggests that Ferb could teach him some moves, but Jeremy is just intimidated. The boys then design an exoskeleton for Jeremy to wear, which will mimic Ferb's moves while he wears a special suit.

At this point, Perry is receiving his briefing from Major Monogram. It seems Doofenshmirtz is buying a lot of ingredients for some evil purpose. He is captured on a platform with his arms and legs shackled spread-eagle, discovering Doofenshmirtz and Norm are preparing for a pot-luck and press conference. A laser slowly fires its way up to split Perry in half while Doofenshmirtz and Norm fly to the meeting.

At the meeting, the evil scientists await with no press present. It seems the dance show is drawing all the press's attention. The scientists barge in on the contest, where they realize only the best dancers get on camera. All the scientists start dancing, but all of them, including Rodney and Doofenshmirtz are horrible.

Jeremy and Candace are doing well at the start, and Jeremy only gets help once contestants start getting illiminated. He does pretty well, either in solo moves or partnered with Candace. He becomes a fan favourite when Ferb starts swatting at a bee, making Jeremy look like an impressive dance move.

Perry is instructed to remove the scientists before they on camera and broadcast their message of evil over the air. Between Perry illiminating scientists, Doofenshmirtz and Rodney knocking out dancers and the judges illiminating dancers, only Jeremy is left on the stage. The host is so impressed by his moves that she invites him to dance on the show every week. Jeremy confesses his help and reveals both the exoskeleton and Ferb's dancing. Candace says that she doesn't mind that Jeremy can't dance and just wanted to have fun. Candace escorts Jeremy 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.
