The song Don't Hurt My Little Sister is performed by Shonen Knife .
There she goes, she ran in her room
She'll probably stay in there the rest of the day
It sounds like it must have been something you said
You know she's awful used to getting her way
Why don't you kiss her?
And while you kiss her
Why don't you treat her
Treat her nice?
Don't hurt, don't hurt my little sister
Don't hurt, don't hurt my little sister
Don't hurt, don't hurt my little sister
You know she digs you and thinks you're a real groovy guy
But yet I'm not sure that I feel the same
We both know that you've been making her cry
I hope you don't think it's some kind of game
Why don't you love her
Like her big brother?
Why don't you tell her
Tell her you're sorry?
Don't hurt, don't hurt my little sister
Don't hurt, don't hurt my little sister
Don't hurt, don't hurt my little sister
