Once upon a time There was a girl and she played so nice Her hair in perfect curls She used to hide the tears in her eyes One morning she woke up with poison on her tongue Thought, "Oh my God, what have I done?" Hand through the mirror, she saw herself clearer There's blood on the gun, I think I should run, it can't be undone Call a doctor I think I created a monster She's got a psycho inside her But I think that I kinda like her She's out for revenge, done playin' pretend Never comin' back, back from the dead Don't act like you were her friend You overreach, and she's six feet under me Got you on your knees, beggin', "Mommy, please?" Girl I used to be, now she isn't me, say, "R.I.P." Call a doctor I think I created a monster She's got a psycho inside her But I think that I kinda like her That's the story of my murder ♪ Call a doctor I think I created a monster She's got a psycho inside her But I think that I kinda like her That's the story of my murder
