Doof: "aah, perry the platypus, wait, who are you?"
Invincible: "I'm not a platypus, I don't know a perry, and I'm-”
*title card*
Doof: "so by invincible you mean the COMPLETELY VINCIBLE"
*doof activates the trap which miraculously works but instead of encasing his whole body it just traps his leg because that's about the height of a platypus*
Doof (CONT’D): "sorry, this thing was kind of designed for platypuses, so you said your name was invincible?"
Invincible: "Yeah"
Doof: "oh, I usually fight this secret agent platypus named perry, I go over my evil scheme while he's trapped, maybe I'll explain my backstory reason for it, he breaks out, beats me, the inator gets destroyed, and he leaves while I say CURSE YOU PERRY THE PLATYPUS"
Invincible: "So wait, you never succeed because of a platypus, it sounds like you wanna fail"
Doof: "well I don't want to, it's just part of the routine, everyone's nemesis is like that, right?"
Invincible: "No, I usually have to go through hell to get any sort of win"
Doof: "hey, guess we're in the same boat then. Say, since perry doesn't seem to be coming, you wanna just fill in for him instead, I was going to show him my ANTI-TRUCK-INATOR"
Invincible: "you know what, sounds like a nice break after what happened with conquest”
Doof: "great, now, I always encounter these noisy, smoky, jacked up trucks. They constantly blocked traffic, tailgated me, and were driven by terrible drivers, so I finally had enough and decided to build my ANTI-TRUCK-INATOR"
Invincible: "ok, easy on the dramatics, I got it the first time, what does it do, exactly? I mean I can guess from the name but how.."
doof: "oh It's a rehash of my old inator, the RUST-INATOR. back during the car competition, oh wait, you're not perry you don't remember that. This new inator will do the same thing but only to those jacked up trucks, turning them into a fine red dust! Still haven't found out the etymology of that, let me look that up again..."
*He leaves to check on his PC and comes back more intrigued*
Doof (CONT’D): "ok, spelled it right this time and I don't think dust had anything to do with it but apparently rust comes from old works for red, huh"
Invincible: "huh, interesting… is this the part where I break out now?"
doof: "oh perry just kind of perfectly times those to just when my schemes about to unfold"
*cut to the inator picking up a Ford dealership*
Doof (CONT’D): "And speak of the devil, so many jacked up trucks to destroy, now to just..."
*Flips the switch, charging up the inator, invincible breaks out of the trap and kicks doof into it, knocking over the inator and conveniently disintegrating Phineas and Ferb's new invention, the tallest ever jacked up truck*
Doof: "curse you pe- oh wait, CURSE YOU INVINCIBLE"
*invincible flies away as doof falls from the building and the inator is destroyed, leaving behind a mattress that conveniently cushions doof's fall*
Doof: I was wondering where my new mattress went.
