[Verse 1]
Your sister liked to go to the drive-in movie
Your sister liked to listen to the radio
I used to think that she got off on the things I hated
She used to call me a Racetrack Romeo

[Verse 2]
'Course she wanted to know you better
I think she knew that it was her own fault
She didn't do it just to make you suffer
I think she did it just to piss me off

[Chorus 1]
So merciless
So merciless, she was
So merciless

[Verse 3]
There's nothin' I could say that would make this better
There's nothin' I could do that could make this worse
No, she didn't leave a note underneath my pillow
No, I didn't find an answer in her purse

[Verse 4]
Yeah, I guess I shoulda seen it coming
It makes me wish I coulda done it myself
After this, I'll probably keep on running
There's a couple miles of highway left
[Chorus 2]
So merciless
So merciless, we are
So merciless

[Verse 5]
Why do people always knock so loud?
Why does everybody seem so lonely?
She would say that I should watch the crowd
Never focus on the faces only

[Verse 6]
Yeah, I guess I should've seen it coming
She was givin' me the wrong advice
My way is a racetrack, honey
With the windows up, it sounds real nice

[Chorus 2]
So merciless
So merciless, we are
So merciless
So merciless, we are
So merciless
So merciless, we are
So merciless
