Lot of Pressure

 is a song featured in The Phineas and Ferb Effect sung by Orton Mahlson and Heinz Doofenshmirtz. In the song, Doof and Orton sing about the pressure they're under being aware of their future selves: Orton being the future creator and star of The Doctor Zone Files, and Doof being the future inventor of time travel.

Lyrics
Orton: They say I'm gonna have a big hit show

With a legion of superfans

I'd be an icon on the Martin television

Sure, writing was my goal, but I'll be honest

I was making backup plans

Because they say, "Write what you know"

But what I knew was the zoning commission

And it should be nice to know

That everything will work out fine

And I'm gonna be a national treasure

Apparently...

But now there's all these expectations

And I'll just... I'll have to realign

That there's a future self of which I'll have to measure

It's just a lot of pressure

Doofenshmirtz: ''Yeah, yeah. Y'know, you think you've got it bad? Ya got nothin' on me, buddy! Listen.''

So, apparently, I'm gonna be the one who finally

Figured out time travel

That's a ton of scientific mysteries

That I'll have to somehow unravel

They'll call me "Professor Time"

There'll be statues of me on every square

So no matter where I go

Oh, look! I'm already there!

Is that what I look like from this angle? Hmmm.

And it should be nice to know

That everything will work out fine

And I'm gonna be a national treasure

But now there's all these expectations

And I'll just have to realign

That there's a future self of which I'll have to measure

Oy vey!

It's just a lot of pressure

(rapping) Yo yo! And who knew we'd be essential?

That we'd have so much potential?

Orton: (also rapping) We could be so influential

Our actions consequential

Doofenshmirtz: We might even rip credentials

I could tell you confidential-

-ly, that you and me

Might have the quality

To achieve a high degree

Of notoriety!

Orton: And get our names on the marquee

Of high society

Doofenshmirtz: And I know now we seem like idiots

Orton: But in the nitty-gritty, it's

So fortunate we're witty

It's gonna make us giddy (Doofenshmirtz:  Yo! Yo! )

When we're someday sitting pretty

But we should be working steady

Gettin' sweaty to get ready

For a future that's un-head-y!

Doofenshmirtz: Yeah, so don't take proposition

To be in this position

Orton: It takes courage

Doofenshmirtz: Premonition

Orton and Doofenshmirtz: (indistinct) condition

Doofenshmirtz: So I'll make this one ambition

Though the beat is slowing, I...

Forgot where I was going with this.

Orton: (whispers) "It's a lot of pressure."

Doofenshmirtz: Oh, yeah!

Orton and Doofenshmirtz: (singing) It's just a lot of pressure!
