Pretty crazy chord changes in the beginning. Pretty sure this is right, though. 
Listen to the song for strumming.

INTRO (over the "whoa oh"s):
F G C E Am G F x 3
F G
C G
C G
C G
C G

VERSE:
C                                          Am
I have often wondered if a pregnant woman is decapitated
G
Will the baby survive? Will the baby survive? Oh oh oh
C                                            Am
I have also wondered if that baby lives its life
G
What kind of life will the baby lead? And will the baby ever be happy? No
C                                                            Am
His heart will be bloated and swollen just like his soul
      G
Too big to fit in his body
C
And I don't think that I can take it
Am
And I don't think that you can take it
G
And I know he sure as hell can't take it
G
So we all go, so we all go, so we all go

Repeat the INTRO here.
