  D6      D*
Stand straight, fall back in line
 D6        D*
Comb your hair, get to work on time
 D6  D*
Everyone, in the big machine
           D6        D*
Tries to break your heart, pull you underneath
  G                 D7sus4/G            G           D7sus4/G (really quick)
Maybe I'm wrong and all that you get is what you see 
  A6                A7                          A6     A
Maybe I'm right and there's something out there to believe
    G           A            D (He pull of his middle finger and puts back on quick on beat 3)
Everybody's talking in their sleep
   G          A               F#                  Bm
Pushing lot of air around and don't say much of anything
   G                    A              Bbm               Bm            A
Except when they're laughing, like some ghosts under a sheet
    G         A                G       D*
Everybody's talking in their sleep

  D6   D*
Watch out, fall back in line
  D6      D*
Trips you up, happens every time
 D6  G*                      Bm
Way down, it's just a big machine
                    D
It can break your heart like anything
  G                 D7sus4/G            G           D7sus4/G (really quick)
Maybe I'm wrong and all that you get is what you see 
  A6                A7                          A6     A
Maybe I'm right and there's something out there to believe
    G           A            D (He pull of his middle finger and puts back on quick on beat 3)
Everybody's talking in their sleep
   G          A               F#                  Bm
Pushing lot of air around and don't say much of anything
   G                    A              Bbm               Bm            A
Except when they're laughing, like some ghosts under a sheet
    G         A                G       
Everybody's talking in their sleep
