Lyrics Knock Yourself Out - Jon Brion

It's something unattainable
That you can't live without
And now the unexplainable
Has you riddled with doubt

Things begin, things decay
And you've gotta find a way to be okay
But if you want to spend the day
Wondering what it's all about
Go and knock yourself out

Why we're put in this mess, is anybody guess
It might be a test or it might not be anything
You need to worry about
But if you're still in doubt
Go and knock yourself out
