Our life is so confusing
No reason and no rhyme
We've got this funny feeling
Getting old before our time

Gimme whachu got!
Gimme whachu got!
I know whachu got!
Gimme whachu got!

What kind of love brings such confusion?
Shuts out the sun and kills all glee?
What are these blues we're here to tell you?

It's sibling rivalry!
I don't wanna share!
I wanna make you nuts!
Gimme whachu got!
Gotta have it all!

Sometimes I see her doing homework
I'm working hard all by myself
And who can stand a happy sister?
He hates I don't require help!

Ooh, ooh, ooh!

I put a spider on her shoulder

Oh, yeah! Ooh-ooh!

I'm not aware that it is fake

Ooh, ooh, ooh!

I ask her what the heck that thing is

I turn and start I scream and shake!

Scream and shake!

Whyy does it feel so good, my dear old fun?
I know it's wrong to feel so mean
You... you should've hear her scream!

I am not blameless in this equation

She likes to talk over my head

Poor Bart, his trials and tribulations

Before a test, she makes me dread

Ooh, ooh, ooh!

'Cause I predict that he will fail

Gonna flunk, ooh-ooh!

I chase her down when she is right

Backing vocals
Ooh, ooh, ooh!

Lisa
When I refuse to just turn tail

Backing vocals
Hold your ground, Lisa

Bart and Lisa
We have our most outstanding fights!

Backing vocals
OUTSTANDING FIGHTS!

Lisa
What kind of love brings such contusions?

Bart
All these Band-Aids the world can see?

Bart and Lisa
What is this shame we're here to tell you?

Bart, Lisa, and backing vocals
It's sibling rivalry!

Bart and Lisa
A brother and a sister
We're trying not to boast
But we can't help believing
That we'll always be this close

Backing vocals
Siblings find it, oh, so hard
When it comes to giving
If they once tried singing background for a living!

Bart and Lisa
A brother and a sister
We will always be this close
