Knock, knock, knock
I'm knocking at your door
'Cause I know what you did the night before
The clothes on the bed don't belong to me
Was I in you head when she was on her knees?
Don't lie to me, I'm smarter than you think

Knock, knock, knock
I'm knocking at your door
I'm not the same girl that you knew before
You've been such a bad, bad boy
Now I've gotta come and take away your toys

You don't get to play with me no more
'Cause you've been a bad, bad boy
You were the cage and now I'm free
But you're playing on your own and you're thinking about me

Who I'm with, what I'm wearing underneath
Taste my skin but only in your dreams
Don't lie to me, I'm smarter than you think

Knock, knock, knock
I'm knocking at your door
I'm not the same girl that you knew before
You've been such a bad, bad boy
Now I've gotta come and take away your toys
You don't get to play with me no more

'Cause you've been a bad, bad, bad, bad boy
Your t-shirt's gone, did she take it home?
She came and left her lipstick on the glass
You've been such a bad, bad boy

Now I've gotta come and take away your toys
You don't get to play with me no more
Cause you've been a bad, bad, bad, bad boy
