Put the sensors on me, my heart is sinking down so quick
I'm not sure if little neurotic me can even try to handle this
There's somebody else on your mind, I feel it in my veins
And the way it's making me uncomfortable is driving me insane
Don't tell me that I'm no longer good enough for you, for you
I don't know if I could take what that would put me through, put me through
I'm up and down and all around just like the devil's carousel
So insanely crazy how this jealousy's been putting me through hell

[Chorus:]
But I do suppose I'm ready for the battle, put on your chainmail
I'm gonna get to fighting because you're mine, and it's time that she knew
She's had her shot and she messed it up, she knows that she failed
It's my turn to give you everything, I've got something I need to prove
If she thinks she's going to win this fight, time to change what she believes
Prepare to set off the cannons if you're not afraid to world war me

Never one to sit back on the sidelines and watch you let go
I'm going to jump through hoops and give you a circus show
You don't deserve her baby, you can do so much better
So don't act like you're giving me a "Dear Jane" letter
She'll never compare to all the things I'll make you feel, you feel
For once in your life don't you want something real, something real?
I'm going to get the guns and fire off all of my ammo
It's time that I let that little homewrecker know

That I do suppose I'm ready for the battle, put on your chainmail
I'm gonna get to fighting because you're mine, and it's time that she knew
She's had her shot and she messed it up, she knows that she failed
It's my turn to give you everything, I've got something I need to prove
If she thinks she's going to win this fight, time to change what she believes
Prepare to set off the cannons if you're not afraid to world war me

Don't you think that you've had your fill of liars, of cheaters?
Every time you see her your feelings for me are getting weaker
I can't help that I feel threatened by the way she looks at you
Give me just one chance and I'll make you adore what I can do

I do suppose I'm ready for the battle, put on your chainmail
I'm gonna get to fighting because you're mine, and it's time that she knew
She's had her shot and she messed it up, she knows that she failed
It's my turn to give you everything, I've got something I need to prove
If she thinks she's going to win this fight, time to change what she believes
Prepare to set off the cannons if you're not afraid to world war me

I do suppose I'm ready for the battle, put on your chainmail
I'm gonna get to fighting because you're mine, and it's time that she knew
She's had her shot and she messed it up, she knows that she failed
It's my turn to give you everything, I've got something I need to prove
If she thinks she's going to win this fight, time to change what she believes
Prepare to set off the cannons if you're not afraid to world war me
