At 0900 hours a UCO, or "Unidentified Crashing Object", landed in our front yard. We've reversed engineered a piece-by-piece duplicate of the strange object. We've called you here to help us discover what this object is and how it works.

— Phineas Flynn

When Doofenshmirtz's latest invention lands in the front yard of the Flynn-Fletcher household, Phineas, Ferb, Candace and Linda try to find out what it does. When Lawrence won't believe Linda about the invention, Candace decides to use him in a way to show Linda Phineas and Ferb's reverse-engineered creation.

Episode Summary

Lawrence is outside putting up a bird feeder and house on a tree. He presses a button and the house opens. He decides that it doesn't do what he wanted it to do but leaves it.

In the living room, Phineas and Ferb are watching a program on reverse engineering. It talks about what it is and how to do it. Phineas asks where Perry is once the program has finished and the scene cuts to Major Monogram asking Carl where Perry is. Carl says he came in early. Since Perry has his mission, Monogram decided to go home.

Perry is already on Heinz Doofenshmirtz's hover jet and they are both fighting. Perry gets caught in one of the many traps that were set. Doofenshmirtz then tells him about one of his first dates. It was with Linda Flynn and they were in a drive-in theater, going to watch a film. Linda says that she would like to be a pop star one day. Doofenshmirtz sarcastically replies that he will take over the world, and she suggests that he should start small and try to take over the Tri-State Area. Doofenshmirtz says it's unlikely but he'll try. He then brings out a machine to make the movie's sound 5th Dimensional and attaches it to their car. Unfortunately, the machine makes the cinema screen explode and blast off into the sky. Whilst finishing his flashback, Doofenshmirtz trips on one of his traps and knocks his latest machine into the Flynn-Fletcher house in the front lawn.

Candace sees the machine and assumes that Phineas and Ferb built it. She calls Linda to see it and says the boys made it. Linda calls the boys and asks what that machine is. Phineas says they didn't build it but they wanted to know what it did. Linda says not to touch the machine, so Phineas and Ferb do some reverse engineering and create a duplicate in the back yard.

Linda phones Lawrence whilst he is in the middle of a presentation about the history of Whiskershire and Chedderton. She asks what that thing was in the garden and Lawrence says that he made it, thinking it was the bird feeder. He says he has to go and cuts Linda off.

Doofenshmirtz is still in one of his traps and presses a button to release Perry. Perry then tries to steer the jet away from Mt Kilimanjaro. The side of the jet hits the mountain and Perry falls into another trap. Doofenshmirtz then comments that his ship has as many traps as a golf course.

In the backyard, Phineas, Ferb, Buford, Baljeet, Irving and Isabella are trying to work out what it does.

In the end, Baljeet and Isabella are having a "romantic" dinner when the machine picks up the candle and is about to destroy it. Phineas tells it to put the candle down and it follows his instructions. Everyone decides that it is an anti-romantic machine.

Linda is still out the front of the house and she phones Lawrence again about the machine. Candace is meanwhile trying to get Linda to see what Phineas and Ferb had built. Candace explains that how Linda feels at the moment is how she feels when trying to bust the boys, but Linda doesn't get it. Candace then says that she always drags Linda to the invention. Linda decides to do the same with Lawrence and drags him out of his presentation. Whilst being dragged off, he asks if anyone has any questions. Everyone puts their hand up but Lawrence is out of the room before he can answer them.

Perry escapes his trap once again put grabs the scepter from the statue of the Earl of Whiskeshire. He activates all of the traps and steers the hover jet again. Perry throws the scepter out of the jet and it hits the machine in the front yard.

Candace is outside talking to Stacy about how she will bust the boys but the machine floats up, covers the mark it made in the grass and flies to the back of the house. It sees the duplicate and they both fall in love. They fly off into the sky just as Linda and Lawrence are getting out of the car. Candace is still trying to show Linda Phineas and Ferb's machine but then she sees them flying off into the sky. She gives up and walks away.

Ferb is telling everyone about if you reverse engineer a heart you get love and lots of mushy red stuff. The episode ends in everyone agreeing with a yeah.

Memorable Quotes

Linda: This song makes me want to be a popstar.

Doofenshmirtz: Yeah right, and I'm gonna rule the world.
Linda: Well, why not?
Doofenshmirtz: Yeah, like I can do that.

Linda: Well, instead of the world, why not start small, like... the Tri-State Area?
Doofenshmirtz: Oddly enough, she did become a pop star and... I'm still struggling with the whole Tri-State Area thing, but the dream's still alive.
Phineas: Ask/bust us what?

Linda: Do you mind telling me what this is and why you built it in our front yard?
Phineas: Umm, we didn't build this, Mom.
Candace: Hah! Quick, bust 'em - wait, you didn't?

Phineas: Not that I'm aware of, no.
Doofenshmirtz: You know, Perry the Platypus, I just...a golf course! A golf course has lots of traps! That's what I should have said.
Perry and Doofenshmirtz are flying over Paris.
Doofenshmirtz: "PIERRE! (Hides and laughs) Did anyone look? I bet, like, half the people down there were looking around like: (French accent) "Who called my name?" (Laughs)
Phineas: Wow, two anti-romance rockets falling in love...
Buford: That's what I call ironing.
Linda: There. Tell me that's not terrifying!

(Candace dances while singing repeatedly "It's a busting feeding frenzy, stay outta the water!")

Lawrence: I'm so sorry I doubted you.
Candace: (dances while singing) It's a busting feeding frenzy, stay outta the water! It's a busting feeding frenzy, stay outta the water! It's a busting feeding frenzy, stay outta the water!

Linda: Wait...But...Candace, where did that thing go?
Candace: Going down down down at the busting feeding frenzy, stay outta the wa-taa! Hmmm. I don't know! But, Mom, you and Dad hafta come to the backyard with me right now and see what the boys are --
(The two robots fly across the sky leaving a heart-shaped mark of smoke and it disappears. Candace looks up and Linda looks up.)

Ugh, never mind.

Background Information

  • This episode depicts Linda mirroring Candace's behavior, trying to convince Lawrence of the strange gizmo as Candace tries to convince Linda of the boys' creations. Despite Candace pointing out this relationship, Linda still doesn't believe her.
    • That being known, it could be implied that Candace's obsession and erratic behavior may have been a trait inherited from Linda.
  • Dr. Doofenshmirtz drove an AMC Gremlin to the drive-in movie theater.
  • The episode shows Linda's aspiration of becoming a pop star and how successful she was fulfilling it in contrast with Doofenshmirtz's aspiration to take over the Tri-State Area as she has suggested and his constant failure trying to realize it.
  • The "Kronk for Hire" cue plays as Dr. Doofenshmirtz educates Perry about- and warns him that he is going to crash into- Mount Kilimanjaro.
  • In the flashback of Heinz and Linda, Heinz is shown with braces. This tells us that at one time he had braces to re-align his teeth, although we do not know how long he had the braces on for.
  • When Doofenshmirtz didn't know what to say "It's gonna be...", and then later in the episode he thinks of it and then says "That's what I should've said," that's really similar to when he couldn't think of it in "Robot Rodeo".

Errors

  • On the drive-in date flashback, Doofenshmirtz's white disco coat turns green when he gets in the car, but goes back to white when the scene changes to the outside POV (when Linda tells him to get the car speaker).
  • As Doofenshmirtz's flashback ends, his mouth does not move when he says "And I never saw her again."
  • They said Isabella was dressed as a Belly Dancer. But she actually was a Hula Dancer.
  • When Isabella was dressed as a Hula Dancer, she had no belly button.
  • In the first scene, when Lawrence was giving a bird house, before he pressed the button it has a pole forthe birds to stand on. But when he pressed the button and it opened and pressed it again it closes and doesn't have the pole anymore.
  • The Roswell UFO incident took place in 1947, not the 1950s.
  • When Linda says "Nobody touches it" a black line can be seen going across the bottom of her neck.

Continuity

Allusions

  • Feeding Frenzy - As Candace dances, she sings "It's a Busting Feeding Frenzy; Stay outta the water!" referencing the game.
  • Julius Caesar (the play by William Shakespeare)- Phineas addresses Isabella, Buford, Baljeet, and Irving as "Friends, Bullies, Irving" similar to "Friends, Romans, Countrymen" from Mark Antony's speech.
  • Lawrence's tale about Whiskershire mirrors the story of The Pied Piper of Hamelin.
  • Towards the beginning of the episode, Phineas and Ferb are seen watching The Uncovery Channel, which seems similar to the Discovery Channel, including the title.
  • Zanzibar is an island off the coast of Africa which is part of the United Republic of Tanzania. Billy Joel also has a track called "Zanzibar" on his 1978 album 52nd Street. However, it's the story of a bar named Zanzibar, not reverse engineering. Zanzibar was also mentioned in "Muppet Treasure Island".
  • American Cinemas - The Drive-in's screen during the Flashback has Dancing Food on it like in the typical American cinemas.
  • The song has a beat that sounds like the hit song from Tommy Tutone's 1981 song 867-5309/Jenny.
  • Friends - Heinz Doofenshmirtz's hair when he was young is similar to the hair that Chandler Bing had in a Friends episode, could both be an allusion to 80s-Techno hairstyles.
  • Hey Arnold! - Candace calls Phineas "Bucko", much like Helga Pataki calls the ones she is bullying.
