Oh
All these villains' minds are tweaked
Since Batman beat
Them into a bloody pulp
They're insane with revenge plans to go delete
Bruce Wayne from his money vault
They're locked in the Arkham Nut House
The Joker's dolled up like a clown, Yikes!
Locked in the Arkham Nut House!
Security's dumb because they all escape
Want Gotham to be their own
Hard to fight Ra's A Ghul cause the man won't age
Working to regain that throne
They're locked in the Arkham Nut House
Watch as Poison Ivy's mean sprouts bite
Locked up in Arkham
Locked up in Arkham
Locked in the Arkham Nut House!
Harley Quinn's mallet will knock teeth out
With Joker on her mind
Catwoman's whip makes you scream and shout
Hurts worse than all her damn feli-li-li-li-li-lines!
"Yo! Watch out!"
Yeah they're locked in the Arkham Nut House
Penguin's umbrella will plow you!
Locked in the Arkham Nut House
Heard that Mr. Freeze told you to "Chill Out"
While at you he shoots ice
With Scarecrow's gas that spreads nightmare clouds
See zombies or some killer mi-mi-mi-mi-mi-mice!
Yo!
When you see that Two Face villain
You'll cringe "Ouch"
Flips a coin to be a threat
Try to figure Riddler's tricky questions out
"What will dry when it gets wet?"
They're locked in the Arkham Nut House
Clayface can look like your spouse, Yuck!
Locked in the Arkham Nut House
Oh
They're out to drive you Batty
Watch your back!
They're locked in the Arkham Nut House
Soon they're free
Now locked in the Arkham Nut House
Ha Ha!
