She Knows - Gnarls Barkley

Up, up and away she goes
Now I know that I know she knows
Could one live a lie?
Well neither will I
If she still try to try
But remarkably, my son,
All my work is done.
Wouldn't surprise me to see her ghost
She would like me to know she knows

And I'm almost sure
I was absolutely nothing before
Now I'm so, so much more
The one word that describes the past
I'm pretty much possessed
We are the reason, I suppose
And we've spoken so I know she knows

There was one to sacrifice
When you live more than twice
Or when I bet it's nice
Gonna be just like you
I'm giving my life, too
No other woman would wear your clothes
And it goes without saying she knows
She knows
