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
