[Joker:]
Take me on home to the asylum
Never alone in the asylum
Anarchy ruled, it was wild
But through it all, you never smiled
Joke's on you, I'm in your head so
Look who's laughing now!

Remember in Arkham City
I killed your girl, so pretty
That was the night you let me die
But when I looked you in the eye
That's when I knew we'd be together
Look who's laughing now!

I'm stuck in your head and I'm laughing!
I filled you with dread and I can't stop laughing!
Your parents are dead and I can't stop laughing!
What else can I do?
Now I'm part of you

I am the Clown Prince of Crime
And we've had a hell of a time
You're part of me, I'm part of you
And now there's nothing left to do
I just can't wait till I'm in control
Who'll be laughing then?

I drove you round the bend and I'm laughing
I'm with you till the end and I can't stop laughing
I killed all your friends and I can't stop laughing
*crazed laughter*
Oh yeah!

Think I can taste your fear
Now that my time is near
I'm in your blood, I'm so alive
I only wish you'd let me drive
It won't be long till I make you kill
Who'll be laughing then?

Barbara's dead and I'm laughing
Jason Todd's dead and I can't stop laughing
I'm even dead and I can't stop laughing
What else can I do?
Now I'm part of you

I drove you round the bend and I'm laughing
I'm with you till the end and I can't stop laughing
I killed all your friends and I can't stop laughing
I'm cock-a-doodle-do
All because of you

I'm stuck in your head and I'm laughing
I filled you with dread and I can't stop laughing
Your parents are dead and I can't stop laughing
*crazed laughter*

I'm stuck in your head and I'm laughing
I filled you with dread and I can't stop laughing
Your parents are dead and I can't stop laughing
What else can I do?
Now I'm part of you

[Robin:]
That's all the bombs disarmed. Time to take down Charisma

[Joker:]
Let's go again!

(Robin knocks Joker into Batman, at which point it shifts back to real POV with Batman clutching Johnny Charisma)

[Johnny Charisma:]
No encore?

(Batman headbutts Charisma, knocking him out)

[Robin:]
And he's a professional singer? Even Alfred sings better than this guy

[Batman:]
Good work, Robin

[Robin:]
No problem. Call it my contribution to music. Let's get golden tonsils here back to the cells
