Oh I hate my brain
            Bm             G
Because the things I think sometimes
            D
Are so judgemental and lame
         Bm           G                
I've got everything I want except
   A
My set of expectations
      Bm       G
Won't stay the same
       A
Then I really really hate my brain
D         G
I hate my brain
          D
I hate my brain


D                    
I used to be a spiderman
  Bm           G          
I used to be a cowboy 
D
from hell

But not anymore

Bm             G
Now I'm just a clam
      A
And I live inside this shell
            Bm      G
Inside this shell I am
       A
Oh god damn I hate my brain
D         G
I hate my brain 
          D
I hate my brain

              G               
And there?s a guy in a(sars?) mask
D                A
Walking down the street screaming
G                         D
The fourth time I've seen something like that
     A
This week
      G
And I just can't shake 
  D                 Bm
I cannot shake that feeling
         A
That one day that man in the mask will be me
D         G
I hate my brain
          D
I hate my brain

   D
Oh I hate my brain
            Bm             G
Because the things I think sometimes
            D
Are so judgemental and lame
         Bm           G                
I've got everything I want except
   A
My set of expectations
      Bm       G
Won't stay the same
A
Man I really hate my brain

D         G
I hate my brain
          Bm
I hate my brain
          A
I hate my brain
          D
I hate my brain
          G
I hate my brain
          Bm
I hate my brain
          A
I hate my brain
          D (hold and fade)
I hate my brain
