Verse 1:
  G
I got to get back to the house
          E                     D
There's a warm chair where the cat has been
                G
I feel a little better when I'm back at the house
E              D
Hope I haven't lost my keys
       G
I been thinking about the police
E                D
Jelly filled for justice, please (also: coffee filled)

  D   C       B

(Main Theme)

Verse 2:
    G
I'm standing here in the kitchen
E             D
Wonder if I'm hungry at all
G
Right there, open the icebox
E               D
Wonder if I can eat it all

| / /   / / | / / / / |
  D   C       B

Final Lyrics:
   Bb                          A
My eyes can't see through this metal door
Bb                A
Mouth just ate an hour before
Bb                          A
Stomach can't remember what food is for
        Bb                                A
Haven't listened to my belly in a year or more

all the chords except where they are written out.
