And then there's this weirdo. It's essentially a Bm7 put down one fret.

The INTRO is played at the beginning, (obviously,) but also after the choruses and the bridge. 
It's just a
G chord, then sliding down your middle finger and pinkie to the 7th fret(relative to the capo),
sliding back up to a chord the shape of a G, just one fret up,
and then back down to the original G. (Watch the video, you'll see what I mean.)

Also, during the kazoo break and the Bridge, he does this thing with the Em chord:
     Em   
E|--3-3-3--3--| 
B|--0-0-0--0--| 
G|--0-0-0--0--| 
D|--2-2-0--0--| 
A|--2-2-0--2--| 
E|--0-0-0--0--| 

Note that you hammer down with your middle finger back onto the D string.
He also does this with the G:
     G
E|--3-3-3-3--| 
B|--0-0-0-0--| 
G|--0-0-0-0--| 
D|--0-0-0-0--| 
A|--2-2-0-2--| 
E|--3-3-3-0--| 

You can lift your middle AND index, then hammer down with the index, but I prefer the method 
tabbed above.

I would recommend watching the video a few times to get the timing during the kazoo break,
(and all the other parts)

So, here it is:

INTRO

VERSE:

Em            C             Em   G     Em
The murderess undresses her late night victim
G                     D                              Em  Bm7 Em
He's got a fine physique, that's why she picked him
G                   D
She takes a swig of port then sits
A             Am             Em          D
Upon his rigor mortised bits till dawn
G                 D    Bm        Em   D   G
She's the sickest lass in all of Sickdom

CHORUS:

D
Sickdom is a realm
            C                  G
Where saintly souls are overwhelmed,
            Em              Bm7                          Em   Bm7 Em
Their grace erased and then replaced with base depravity
D                              G                C
Its denizens are menacing, yet fill you full of calm
           Em      D               G
By shoving opiated balm up in your cavity...

INTRO

VERSE:

       Em            C         Em  G    Em
The murderess confesses to the handsome priest
            G         D                     Em  Bm7 Em
But he doesn't hear a word, as he's deceased
G                     D
She tears his frock & socks off and
A                   Am           Em            D
Prepares to get her rocks off by smearing him
G                         D    Bm               Em  D    G
In the extremely unctuous gunk with which she's greased

KAZOO BDA K
D  G  Em  “W”  Em  Bm7 Em D G  Em Bm7 Em  D G

BRIDGE:

       D                   Em
The murderess caresses her machete
        Am                     Em
And curls up on a deep magenta settee
      D                               G
The scent of fetid gent is strong and heady
       A                D6                G
As she slips out of her pinkish patchwork teddy

INTRO

VERSE:

       Em       C            Em   G   Em
The murderess's tresses grow gray and thin
              G        D                Em  Bm7 Em
And then the ravages of time do her in
      G              D
She punts across the Styx to dwell
       A           Am               Em       D
But cannot get her kicks so well in Hades,
            G            D    Bm       Em   D       G
Where cavorting with the dead is not a sin, rickety-tin,
        Em                D           G D G
How she longs to live in Sickdom once again…
