G                          D
   Up to my ears in bitter tears
                   Em
Can't believe ive sunk this low
      C                 D 
As I walk the planktom, Inner sanctum
G                           D
Got outta dodge, sailed on a Bonless Bon Voyage
          Em                                
You said North, I headed south, 
             C                         D
tossed overboard, Good lord thats a really large mouth

(CHORUS)

Em       D            C           D
   I'm sleepin' with fishes here
                     Em
(In the Belly of the Whale)
Em       D            C           D
   I'm highly nutritious here
                     Em
(In the Belly of the Whale)
Em       D            C           D
   Bad food, Lousy atmosphere
                     Em
(I don't wanna bellyache)
Em       D            C
   How long is this gonna take?
(VERSE 2)

G                          D
   Woke up this morning kinda blue
                   Em
Thinkin' throught that age old question
      C         D 
How to exit a whale's digestion
G                               D
    It might behoove me to be heaved
          Em                                
Head out like a human comet 
             C                    D
(hmm, i wonder what rythmes with comet)

(CHORUS) 
Em       D            C           D
   I'm sleepin' with fishes here
D                     Em
(In the Belly of the Whale)
Em       D            C           D
   They say i'm delicious here
                     Em
(In the Belly of the Whale)
Em       D            C           D
   Lord please make him chuck it all
                     Em
           (Its a gut call)
Em       D            C       D
   In the belly of the whale 
Em
(I'm in the belly)


(RAP)
(same chords as the chorus)
In the belly of the whale
It's an underwater jail
It's a tight squeeze
It's a-gettin to me but its roomier than the tail

Hey sailor let me flow free
like a salmon to the sea
from the L.A symphany
I'm a 

Paddle-Boat Paddling in their wake
Fake freestyler
but my unemployment pays
im avoiding cliches like

Whale of a tale and
you cant keep a good man down
cos u cant, cos a been there man
