[Joker:]
Take me on home to the asylum
Never alone in the asylum
 [bad word]  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 [bad word] 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 [bad word] 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
