Hey Ferb, I know what we’re gonna do today! Destroy these 2 mistakes
Heck, we could this all the time, 24/7, anyday! Ferb:
I may not talk a lot but I have the action to spit some rhymes
This dumb big-nose and gothic blonde are just wasting their time Phineas:
What makes you think you can win this? We got a band back together
So the chance of you two winning is obviously never Ferb:
Billy’s retarded, so your chances of winning are very grim
And your adventures, they aren’t even worth anything
How can Ferb even rap, when he doesn’t say a single word
We’re Billy and Mandy, duh, you’re about to be served Mandy:
You dummies, stop rapping and fix your head shapes you pricks
How can you beat us when you don’t know where Perry is? Billy:
You winning this battle might be in the 2nd dimension
Yes, I might be an idiot but at least building stuff is not in my attention Mandy:
You two are flop stars, not stars, your inventions are pure bull
Your show got really terrible when you made that crossover with Marvel
Call this your summer vacation, because you’ll never make us get schooled Ferb:
These failures of a duo think they’ve won? They must be fooled Phineas:
Stop relying on creepy shit, you should’ve never been born Ferb:
After this, you’ll be left like Doofenshmirtz; torn! Phineas:
Hey, Ferb, let’s make an invention! It’ll be their Endsville Ferb:
That’s a brilliant idea, they never had any skill Phineas:
We’ve already made you grim, ‘cause the tides have turned Both:
You two just got burned by Phineas and Ferb!
You can’t handle all these Grim Adventures that we got!
You do the same routine every episode and your sister never had you caught
We’ll run over you with the Go-Kart 3000
Just go back to making stupid shit, like a whole entire mountain
Your only number one fan was a fucked up geek
And I’m gonna kick your ass like Chicken Ball Z, you freaks
We'll leave you both in shame after your machines have rusted
Billy and Mandy have won, and you two have been busted!
