(At Middleton High)
Kim: It feels great to be myself again!
Ron: I could not take another day of...
Tall bully: Hey, Stoppable!
Ron: Oh, no! Is this D-hall?
Tall bully: (gives some money to Ron) Here's that money I've been, uh, "holding" for you. Since Kindergarten?
Small bully: Hey, got this new video game. Enjoy!
Ron: What just happened?
Kim: When I was still in you body, I went back to D-Hall. Gave some sensitivity training. No big. (edit) (After escaping Drakken's exploding lair)
Ron: Good news, we're all back in our bods, bad news, I think we neutronalized the Neutronalizer.
Kim: Or not
(the Neutronalzier still stands)
Dobbs: Did I neglect to mention that the Neutronalizer is dang near indestructible?
Ron: I know someone like that
Kim: Back at 'cha, brain switch boy! (edit) (Drakken and Dobbs switch bodies, back to their original)
Dr. Drakken: Oh, there's no body like my body!
Dobbs: Oh, yes sir, it's good to be home!
(Two henchmen takes Dobbs away)
Henchman: Alright, let's go!
Dr. Drakken: Shego! Initiate Neutronalizer firing sequence!
(It starts, but shuts down quickly)
Shego: I don't think so!
Dr. Drakken: What?
Shego: Your brain thing blew out the power. Smooth move.
Dr. Drakken: Cheap rental lair! They know that I have excessive power demands! (the Kimmunicator beeps, and Drakken takes it) Kim can't talk right now, can I take a message?
Wade: Tell her the army is on the way!
Dr. Drakken: The army? Well, that's just dandy! Shego! Activate the automatic self-destruct mechanism.
Shego: With pleasure!
(She hits the self-destruct button)
Computer: Lair self-destruct initiated
Kim (in Ron's body): You can't just destroy this place
Dr. Drakken: So I lose the security deposit. It's worth it.
Ron (in Kim's body): But that will blow up the brain switcher! We'll never get back to normal!
Kim (in Ron's body): Ron, we'll be blown up too.
Ron (in Kim's body): Oh, man!
Dr. Drakken: Farewell, Kim Possible!
Computer: The lair will self-destruct in 60 seconds.
Ron (in Kim's body): We're doomed!
Dobbs: No, we ain't!
(Dobbs frees Kim and Ron. Kim grabs the Kimmunicator)
Kim (in Ron's body): Wade, we have very little time and no power! Thoughts?
Wade: The tri-lithium core I designed through the Kimmunicator
packs a punch.
Ron (in Kim's body): There's no way that little thing has enough power
Kim (in Ron's body: It's our only hope!
Computer: The lair will self-destruct in thirty seconds.
(Kim and Ron switches back)
Kim: It worked! I'm me again!
Ron (In Rufus' body): Uh, guys. We have a problem!
Rufus (in Ron's body): Big problems
(Ron and Rufus switch bodies)
Computer: The lair will self-destruct in ten, nine, eight, seven, six, five, four...
Ron: Buddy!
Computer: ...three, two, one,
Dobbs: We'd best be gettin' out of here! (edit) (Kim and Ron are heading for Drakken's lair)
Wade: (In Kimmunicator) Drakken did an excellent job covering his tracks, but he wanted his mail forward. The change of address card shows him in some kind of timeshare lair complex... suite 7B.
(they try to enter from behind)
Ron (in Kim's body): Oh yeah. Like he's just gonna leave the backdoor open.
(they try to open the backdoor. It was open, and they sneak in)
Kim (in Ron's body): Over there!
Dr. Drakken (in Dobbs' body): Oh! Issuing an ultimatum isn't what it used to be. Give the world a deadline and what do you get? Nothing. Nada. Zip.
Shego: Gee. You think it had something to do with the puppet?
Dr. Drakken (in Dobbs' body): Argh! (pause) They say Paris is lovely this time of year. Well, not anymore! Enter coordinates!
Kim (in Ron's body): We gotta move fast. Ron and I are will draw Drakken and Shego away, then you disarm the Neutronalizer.
Ron (in Kim's body): How come I finally get the chance to be you, and I still end up the distraction?
Dobbs (in Drakken's body): Uh, miss Possible? I don't know the first thing about disarming the Neuronalizer, I just guarded it.
Ron (in Kim's body): O-kay, new plan.
(Blue energy blasts destroy the crate they hid behind)
Dr. Drakken (in Dobbs' body): No new plans. (To Kim in Ron's body) You're finished, Kim Possible!
Ron (in Kim's body): (with a high, fake voice) But I'm Kim! Finish me!
Dr. Drakken (in Dobbs' body): Oh, please. I know all about your switcheroo, buffoonish sidekick!
Kim (in Ron's body): Don't insult him. He's got it hard enough! Trust me.
Ron (in Kim's body): Me? You should try going through a day as Kim! The pressure's intense!
Dr. Drakken (in Dobbs' body): What does this has to do with anything? Finish them both!
(The henchmen go after Kin and Ron.)
Ron (in Kim's body): Heee. Whoa, give me a break here. I'm wearing a skirt.
Kim (in Ron'd body): Now you know what it's like.
(Two henchmen take Dobbs.)
Dr. Drakken (in Dobbs' body): I want my body!
Dobbs (in Drakken's body): Oh, y'all can have it! It's ugly and it itches something fierce! (edit) (At Drakken's timeshare lair)
Dr. Drakken (in Dobbs' body): Time to deliver my ultimatum! (Shego laughs)
Dr. Drakken (in Dobbs' body): And just what is so funny?
Shego: Your voice. That body. It's not exactly the stuff for ultimatums
Dr. Drakken (in Dobbs' body): Very well!
(we skip to his ultimatum video, which is a puppet moving to his voice)
Dr. Drakken (in Dobbs' body): Declare me supreme ruler of Earth, or I will neutronalize a different major city every hour on the hour. (he trows away the puppet) That should do it.
Shego: What does "neutronalize" mean anyway?
Dr. Drakken (in Dobbs' body): I have no idea, but the military had it, and it was top secret, that's good enough for me. (edit)

This episode features the first mention of Professor Dementor, although he doesn’t appear until later on in the series. (edit) When Ron and Kim switch minds, Rufus activates the machine by landing on a button on the control panel. However, for every mind switch after this, a lever is pulled to activate the machine. (edit) Ron and Kim shouldn't have kept their own voices when they switched bodies, because voices are part of the body, not the brain. (edit) When Shego is shown laughing after Dr. Drakken says, "Time to deliver my ultimatum.", her face is flesh colored. (edit) If Drakken's brain switch machine blew out all the electrical power, there shouldn't have been enough power to turn on the self destruct mechanism. (edit)

Dr. Drakken: I will destroy a major city every hour on the hour!

Dr. Drakken's ultimatum is almost the same as Dr. Evil's (from Austin Powers) ultimatum. (edit) Star Trek:

The first brain switch sequence where the images of Kim and Ron ghost out and switch bodies is based on the opening scene from the final Star Trek original series episode Turnabout Intruder where Dr. Janice Lester (an old flame with vengeance on her mind) uses an alien machine to switch bodies with Captain Kirk.
