Okay, I watched a video on YouTube and they played an acoustic version of it. It got 
but I thought you guys might like this. :D
When it gets to the 'BANG BANG!' part, I like to tap my guitar's bridge. So feel free to 
that, too. (:

So baby tell me
What's the deal with your new boyfriend?
He wears a hat to the side with a bill he doesn't want anyone to bend

BANG BANG!
I heard a knock at the door
She walked in, it's a sin to keep her begging for more
BANG BANG!
I watched her clothes hit the floor
I could never say no

CHORUS:

Bm (x24432@1)           DIt's (xx0232@1)a game, she's to blame
                   G (320003@1)      EmBut (022000@1)who's keeping score?

So baby tell me
How does it feel to break and bend?
You just can't choose between us two
It's a game you'll always lose

BANG BANG!
I hope that's him at the door
Will the truth finally find her?
BANG BANG!
Will she run, will she hide?
The truth's creeping up slow

Bm (x24432@1)           DIt's (xx0232@1)a game, she's to blame
