It was Brown and it had raisins
       G
And we flushed it for those reasons
          Dm                   C
This is a poop song, this is a poop song!
      C
I was walking to the mall
      G
and I had to make a poop
          Dm                   C
this is a poop song, this is a poop song!
C                G           Dm               C
We pooped at the mall today, We pooped at the mall!
