"I Go Looney" is a villain song sung by the Joker (voiced by Mark Hamill) in the 2016 animated superhero film Batman: The Killing Joke which is loosely based on the 1988 DC Comics one-shot graphic novel of the same name.


When the world is full of care

And every headline screams despair,

All is rape, starvation, war and life is vile

Then there’s a certain thing I do

Which I shall pass along to you,

That’s always guaranteed to make me smile:


I go loo-oo-oony as a light-bulb battered bug!

Simply loo-oo-oony, sometimes foam and chew the rug!

Mister, life is swell

In a padded cell,

It’ll chase those blues away:

You can trade your gloom

For a rubber room

And injections twice a day!

Just go loo-oo-oony like an acid casualty,

Or a moo-oo-oonie, or a preacher on T.V.

When the human race

Wears an anxious face,

When the bomb hangs overhead,

When your kid turns blue,

It won’t worry you,

You can smile and nod instead.

When you’re loo-oo-oony, then you just don’t give a fig,

Man’s so pu-uu-uny, and the universe so big!

If you hurt inside,

Get certified,

And if life should treat you bad…
