We Are Scientists

I got this whole thing figured out
I guess I better write it down, now
'Cause presently my memory's not terribly sound
Everything is twice around, now
It shouldn't be this hard
I guess I'm not as smart
As I'd like to think I am
And even though you won't
Admit it now I know, you know, I know, you know
I guess it isn't any news
This keeps coming out in two's
If history repeats itself then what can I do?
Nothing I can say is news to you
It shouldn't be this hard
