I'm ace at all anatomies and master of dissection

An expert chef who wields an expert knife

But still, I sense a gremlin in the system of perfection

There clearly are still mysteries to life

It's kingdom file class item, it's order family genus

It all comes back to me like child's play

When she leans over my shoulder there in all her long and leanness

It cuts my heart of knowledge clean away (clean away)

I try to keep a focused mind and steady hand

(Ooh, keep focused, ooh, keep steady)

But the rhythm of my heart is like a country western band

(Oh, oh, oh, oh)

Oh, biology!

What have you done to me?

Why can't my grown-up brain control my teenage parts?

Oh, biology!

Why won't you let me be?

Why can't you be humane and still our beating hearts?

Before the cutting starts

Huh, shyeah, Ellie, check it, hahaha, man

He's inert and inarticulate (ooh), a specimen of truant (ooh)

And though we're both 16, he's much too young (ooh)

(Much too young)

My amygdala is fully formed, my frontal lobe is fluent (ooh, ooh)

And pheromones go foxing with my tongue

That's totes amaze, I'm way impressed, like, sweet technique

Holy cow!

Um, like totally, um, thanks

Good Lord, now can't I even speak?

Oh, biology

What have you done to me?

My over 40 soul is in a teen cliché (teen cliché!)

Oh, biology

Why won't you set me free?

'Cause I'm not in control and hunger has its say (hunger has its say)

And hormones have their way

Focus, Blake, focus

Hey, take a look at Ellie Blake, she does this lab work great

For Kermit there, he had no chance

That girl is on my nerves today, I better set her straight

It's fun to make a dead frog dance

I never knew that Ellie Blake was such a science wiz

She's smart, of course, so it makes sense

But something's up with her today, I don't know what it is

She's like on fire, she's so intense

He's so intense (it's so intense)

And I'm so danced

Oh, biology!

Look what you've done to me!

My heart is in a pan, my brain is out to sea

Oh, biology!

Why won't you let me be?

Please help me if you can, please hear my painful plea

Biology

Biology

Biology

Please set me free

Set me free
