Verse 1:

Em7    D     Cadd9
There are no words, to paint a picture of you girl
Em7   D          Cadd9
Your eyes, those curves, it's like you're from some other world 
Em7  D      Cadd9   
You walk my way, oh God its so frustrating.


Pre chorus:

Cadd9
So why do I disappear when you come near, 
D
It makes me feel so small, 
Cadd9
Why do I blow my lines, most every time, 
D
Like I've got no chance at all.


Chorus:

G                   Dadd4
If I could be your superman, 
   Dmadd4          Cadd9
I'd fly you to the stars and back again. 
G                    Dadd4

But I can only write this song, 
    Dmadd4           Cmaj7
And tell you that I'm not that strong.

'Cause I'm no superman, I hope you like me as I am.

Em7        D        Cadd9

You say my name, oh God I can't stop shaking.
