Little riff bit (main notes only):
 | -------0-----------0---------- | 
 | ---1-3------1--1-3--------1--- | 
 | --------0-2---------0-2------- | 
 | ------------------------2----- | 
 | ------------------------------ | 
 | ------------------------------ | 
Or you can play the chords like this:
 | ---0-0-0--0--0--0-0--0--0--0-- | 
 | ---1-3-1--1--1--1-1--1--1--1-- | 
 | ---0-0-0--2--0--0-0--0--2--0-- | 
 | ---2-0-2--3--2--2-0--2--3--2-- | 
 | ---3-2-3--3--3--3-2--3--3--3-- | 
 | -----3------------3----------- | 
Which are basically C, G and F and so I shall label them as such!

Intro: riff/chord version

Verse 1:
C5                F5       C5
Black infectious wind we breathe,
C5                       F5         C5
Fills up the bored hole that lust leaves.

Chorus:
   F5 C5 G5
He yawns,
    F5  C5     G5
She yawns as well.
    G5                   C5
She yawns because she's bored,
   F5       C5        F5           G5  C5
He yawns because he can't sleep anymore.
  
Verse 2:     
        C5                                             F5
They go out, fill their mouths with drink and food so they don't have to 
C5
speak.
    C5                                                   F5
And in between courses they're gasping for air, so they yawn and look at 
      C5
their feet.

Chorus:
   F5 C5 G5
She yawns,
    F5  C5     G5
He yawns as well.
    G5                   C5
She yawns because she's bored,
   F5       C5        F5           G5  C5
He yawns because he can't sleep anymore.

Interlude (kinda thing):
Riff bit/chord version

Chorus/outro:

    F5 C5 G5
She yawns,
       F5   C5    G5
And he yawns as well.
   G5                  C5
He yawns because he's tired,
    F5            C5          F5          G5            C5
The girl that he slept with sleeps too soon at night.
         G5                   C5
When she yawns she tells the truth,
         F5        C5               F5            G5         C5
That the boy she adores is just a man she's contracted to.
    G5               C5
But what of you and me?
  F5               C5               F5        G5      C5
Admit that you're bored, you need more electricity.
     G5             C5
I've had enough of love, 
   F5         C5        F5        G5     C5
It just ends with two yawns in unison. 

G5 C5 F5 C5 F5 G5 C5
