The Episode

Phineas: Candace, it's your turn to clean up the living room today!

Candace: But... I-I did last yesterday! Yeah, I did that!

Phineas: Come on, Candace...

Candace: Ha! You can't prove that it's my turn, because Mom and Dad was away yesterday.

Phineas: (turns around to Ferb) Ferb, I know what we're gonna do today! We're gonna build... a lie-detector!

Phineas and Ferb starts to work on the lie-detector, when Buford, Baljeet and Isabella arrives.

Isabella: Hi Phineas Hi Ferb! Watcha doin'?

Phineas: Today, we are building a lie-detector!

Isabella: Really? That's so cool!

Baljeet: Awsome!

Phineas: Hey, where's Perry?

Perry is inside the house. He presses a button hidden in the Camel-lamp. An underground passage opens and Perry climbs down.

Carl: Ahh, Agent P! Major Monogram is sick today, so I'm giving orders today! Ahem! Dr. Doofenshmirtz has bought something from a petshop, find out what he bought and find out why!

Perry makes salutes and runs off.

Phineas: Now it's done!

Baljeet: Who will test it out first?

Everyone looks at Baljeet

Baljeet: Why do I have to test it first? Maybe it will erase my brain!

Phineas: Relax, it's harmless!

Baljeet: Oh well...

Baljeet walks over the machine and sits down on a chair. Ferb puts a helmet on Baljeet.

Phineas: Okay, we are gonna ask you a question, and if what you say is true, this lamp will be green, but if you lie, the lamp will get red. Understood?

Baljeet: Okay, ask away!

Phineas: Hmm... do you think you're smart?

Baljeet: Well, yes, yes I do.

The lamp flashes green

Isabella: Who is your crush?

Baljeet: WHAT? Uhh... no one..

The lamp flashes red

Baljeet: Eheheh...

Buford: Are you a nerd, nerd?

Baljeet: Nooo.....eheheh...yes?

The lamp flashes green

Phineas: Well, the lie-detector works perfectly! Now, let's test Candace.

Perry knocks on Doofenshmirtz door.

Doofenshmirtz: Ohh, Perry the Platypus! Come in, come in, don't be shy!

Doofenshmirtz: You maybe wonder what I'm up to, hmm? Well, it has nothing to do with the petshop, as Carl told you... eheheh...

Perry glares at Doofenshmirtz.

Doofenshmirtz: Well, I guess I have to trap you.

Doofenshmirtz picks up a remote and presses a button so a cage falls down on Perry.

Doofenshmirtz: Aww, I thought you would fall for the petshop thingy. By the way, I just went in there to look at the animals... Well, now it's time for my evil plan! I installed spy-cameras all over the O.W.C.A-lair! So I could see you get your mission! Yes, Perry the Platypus, if I show people this video, O.W.C.A is gonna close, because it's top secret, and then you won't be an agent anymore, and then... then I can take over the Tri-State-Area!! AHAHAHAHAHA!

Phineas walks into the house

Phineas: Candace?

Candace: (talks to Stacy throught her cell-phone) And I was like, oh no you didn't, and she was like, oh yes I did, and I was like...

Phineas: Candace! Come, look what we've made!

Candace: Sorry, Stacy. My goofy brothers are up to something again. C.Y.A B.F.F!

Candace: This better be good.

Phineas: Come and look!

Candace followes Phineas and Ferb to the backyard.

Candace: What is...that?

Ferb: It is a lie-detector that reveals if you are a lier or not.

Phineas: Wanna give it a try?

Candace: Oh no, no way I'm gonna test that...thing! It could erase my brain!

Baljeet: Told ya'.

Ferb: Also, another good lie-detector is that if you don't wanna test it, it means that you hide something.

Candace: No, I don't... but... I... Fine: Test me!

Candace sits down on the lie-detector chair grumpy. Ferb puts on the helmet.

Phineas: Okay, do you like us?

Candace: You and Ferb? You're my brothers, duh. I like you like a sister likes a brother.

Light flashes green

Phineas: Okay... now for the real thing... did you clean he living room yesterday?

Candace: I... I d-did it... y-yesterday...

Light flashes red

Candace: Don't say a word!

Candace leaves and goes to the living room and starts grumpy to clean the living room.

Doofenshmirtz takes another remote from a shelf.

Doofenshmirtz: See this, Perry the Platypus? Yes, with this remote, I can controll the spy-camera! If I press this button, all the cameras will be POOF! Gone! Oops.. Maybe I should not tell you that...

Perry liftes the cage and is free.

Doofenshmirtz: Aww, man! I knew I should have bought that heavy cage...

Perry snatches the remote from Doofenshmirtz hand and presses the button that makes the cameras disappear.

Doofenshmirtz: NOOOOOO!

Doofenshmirtz takes a third remote from the shelf.

Doofenshmirtz: Taste this! AHAHAHA!

Doofenshmirtz shoots lazer with the remote.

Phineas: How about you, Isabella, do you wanna try?

Isabella: Gladly...!

Isabella sits on the chair and Fer puts on the helmet.

Phineas: Ready?

Isabella: Ready spaghetti!

Phineas: Okay... hmm... do you think that I am a nice guy?

Isabella thinks to herself: This is your chance, Isabella! Today I'm gonna tell Phineas the truth!

Isabella: Yeah, but you are more than that. I lov--

A beam of lazer from Doofenshmirtz remote hits the lie-detector.


Isabella: EEK!

Buford: Oh man, it's gonna explode!

The lie-detector explodes. BOOM!

Phineas runs to Isabella that lies on the ground.

Phineas: Isabella? Isabella?!

Isabella: I'm okay... but it feels like my brain got erased!

Baljeet: I told you, I told you!

Isabella: No, Baljeet, I mean that I am chocked...

Baljeet: ... oh.

Perry snatches the remote from Doofenshmirtz hand and shoots all the other remotes and then he throws the remote from the building.


Perry jetpacks away from Doofenshmirtz, heading home.

Phineas: Oh, there you are, Perry!

Perry: Gyurururu....
