I'm not entirely sure if I've got the chords right, but I think it should be something  
like this. 

This is my first tab, so please rate and comment! :) 

Standard tuning. 
Verse: G - Em - G - Em 
Chorus: G - D - C / Am - D / G - D - C / Em

The intro would go like this: 
e|------------------------------------------------------------------| 
B|--------------------------0-3-------------------------------------| 
G|----0-----0---0--2-0-2-0-2---------0-----0---0--2-0-2-0-2-0-2*-0--| 
D|2-2---2-4---0----0-------------2-2---2-4---0----0-----------------| 
A|2----------------0-------------2----------------0-----------------| 
E|0------------------------------0----------------------------------| 
   *is where the verse starts, "Oh this-" 

verse 1: 
        G                      Em 
Oh this feels like the Kennedy Curse 
     G                    Em 
And everything inside is dead 
           G                      Em 
I'm on the fence about what feels worse 
        G                     Em 
The one leaving or the one in bed 


verse 2: 
     G                            Em 
In a dream she's talking dirty to me 
          G                     Em 
Just in a language that I can't speak 
         G 
Then she kisses my scars 
       Em 
As she cuts out my heart 
    G                      Em 
And places it right on her sleeve 


verse 3: 
           G                          Em 
I'm having visions of the way it will end 
      G                    Em 
I can see it all now in my head 
         G 
You will cast the first stone 
    Em 
My sail will be torn 
             G                    Em 
I'll lose my vessel to a dark sea bed 




[Refrão]
G                 D                C       (D) 
Will someone just come and take my heart 
G              D               C        (D) 
Set it down in front of moving cars 
Am                 D 
 I feel nothing at all 
   G                  D                C 
So won't someone just come and take my heart 
             Em 
And tear it apart 

(A/N: (D) is an optional chord to be played at the last beat) 

verse 4: 

      G                       Em 
Oh my thoughts they remain perverse 
      G                         Em 
And I know I am the first of my kin 
      G 
To be born with this curse 
   Em 
So persuade and coerce 
            G                   Em 
Because I'm willing to be born again 


Chorus: 

G                 D                C        (D) 
Will someone just come and take my heart 
G              D               C         (D) 
Set it down in front of moving cars 
Am                  D 
  I feel nothing at all 
   G                  D                C 
So won't someone just come and take my heart 
             Em 
And tear it apart 

("And tear it apart" repeats for a few times before the song ends, it's the same chord  
all the way, so you can improvise)
