Chuckling and roaring... Outside in my shed
Mad scientist with a psycho quest
I'll shove a hook in her brain and I'll replace her head

Mutant supplies help create my bride
Transformed this girl when circuits fried
In my strange lair I'll labor and switch her genes, Yikes!
My gourd isn't screwed on right

With some careful snips I'll make Ruth my babe
I'm swapping out brains today!
Once she was quite dumb, She'll be witty and brave
I'm fixing her brain today!
Yeah! Now a Yale chick from my scalpel she's saaaaaaaaaaaaved
I'm mending her brain today!
Wicked sharp are those dames I crave
Repairing her braaaaaaaain...
I'm swapping out braaaaaaaaaains.... Today!

Hearing screams... I grin...
Knocked her out, She'll be happy I did
With this vial she will ace each equation that's quizzed

So sick of mindless babble these tongs will squeeze
Her simple old mind and toss it away
Don't need her moronic thinker just her massive rack
Thus I'm gonna hack for a skull that's well-packed

Love when that gal strips but her head's misplaced
I'm swapping out brains today!
Though she has tight buns it's a pity she's spaced
I'll restore her brain today!
Yeah! She has sexy hips but her wits are erased
Rebuilding her brain today!
Stares at that box that says "Concentrate"
I'm replacing braaaaaains...
I'm juggling braaaaaaaains...
I'm swapping out braaaaaaains... Today!

[Mad Scientist Guitar Solo]

Once shopping for brains...
Now chopping up brains...
I'm popping out braaaaaaaaaains... Todaaaaaaaaaaay!
I'm swapping out brains today!

Yeah! Think I've earned a girl who's shrewd, She's intelligent!
From mopping up brains today!
And I dyed her blonde hair to dark brown, Dumb blonde's slain!
I'm dropping those brains today!
Yo! What's with this weasel here in my shed? Oh man...
I'm screwing up brains today!
It's paws have strangled my neck... Cause I'm insane!
Oops! I made a huge mistake!
Mislabled thooooooooooose brains
I'm mixing up brains today!
Not fixing her brain... Today!
Oy vey!
