I Knew You Were Trouble Parody

Once upon a time, before I was insane
 I dated this Disney guy, Joe Jonas was his name
 But he broke up with me
 You're just way too creepy!
 Plus I found someone else, his name's Mickey!
 So, I wrote a song about his stupid ass
 Then found this guy named John
 But that was over fast
 If you don't marry me, I will pull out your teeth!
 You're totally crazy! (no) yes (no) yes (maybe!)
 He hit me with his guitar
 And he said that
 We are through!
 Just you wait until I write a song about you!
 Then I met that Jake Gyllenhaal dick
 And was obsessed right away
 You've sent me 1,000 messages, and that's just from today!
 Oh, that's because I'm having your baby!
 What?! But you don't even put out!
 Stop questioning me, Jakey
 Or I'll put you 6 feet underground!
 Whoa! Whoa!
 Psycho, psycho, psycho!
 Fine, go!
 It's good material!
 Next came Kennedy, I think he was fifteen
 I bought the house next door to watch you constantly
 And also to make sure, you never ever cheat!
 OMG we are done, you are scary!
 Harry was my last, that One Direction freak
 I taped him to my wall, so he could never leave
 Someone call the police! You're insane, we are through!
 You're just like all the rest, what did I do to you?
 So I used my stalker app
 To track down all of those pricks
 The next song I write
 I'll use their blood as my ink! (hey!)
 Holy crap, that nut job just bursted in! (Ahh!)
 What the hell is this?
 It's a support group for all the men you wrote songs about, you bitch!
 What? I have not written about Harry yet!
 I am just planning ahead!
 Why are you even here anyway?
 To finish you all off with my pen!
 No! no!
 Devil! devil! devil!
 Ow! Ow!
 It's true, I'm the devil!
 OK, that's enough!
 You were right, she's nuts
 You are coming with us
 Wait, what? Get off of me, I'm not crazy!
 It worked!
 This was all a trick, we knew you would come
 So we hired this doctor
 You're going to an insane asylum
 Based on the behavior I observed
 Ow! Ow! Let me go, you assholes!
 No! No!
 Welcome to your new home
 You're crazy too, huh?
