I Saw an X Ray of a Girl Passing Gas

Are you ready to rock?
Well, rock on!
Pardon me, I'm only bleeding
But you cut me to the bone
My imperfections have reduced you
To a lowly animal
Part of me
Was introduced to you
Then it walked right
Out the door
And tonight
You're probably feeling
Like a human cannonball
It used to be
That loving you
Was easy...unrestrained
But now
I'm only bleeding
But I'm loving
Only pain
Pardon me, I'm only bleeding
But you cut me to the bone
And tonight
You're probably feeling
Like a Human Cannonball
