This is my first tab, I figured it out by listening to this vid:
http://www.youtube.com/watch?v=Ut8j2X2eAxk

Common time; Key of C

(listen to the track for chord changes, it's actually quite apparent when they do)

Intro: C    Em|Am    G|Dm     |Dm     G| (and repeat once)

Verse: 
    C (x32010@1)                    EmI (022000@1)built a man made out of bricks
      F (133211@1)            G (320003@1)and lived inside his chest
   C (x32010@1)                      EmI (022000@1)beat my hands against the walls
           F (133211@1)            G (320003@1)To make a heart beat in his breast
  F (133211@1)                         G (320003@1)I smashed my fist against his ribs
    C (x32010@1)     Em (022000@1) Fto (133211@1)suck the air inside
    F (133211@1)                Gand (320003@1)swing by swing and blow by blow
  F (133211@1)                 GI (320003@1)brought that man to life (hold G for one more bar)

Intro again (omit the Dm and G though)

C    Em|Am    G| (repeat)

Verse II: (arpeggiated)
    C (x32010@1)                    EmI (022000@1)built a man and cut his skin
     F (133211@1)              Gand (320003@1)lived inside his heart
   C (x32010@1)                   EmI (022000@1)pumped it with my fingertips 
     F (133211@1)              Gand (320003@1)loved it from the start
          CAnd (x32010@1)with every beat I gave him
  F (133211@1)              Fm (133111@1)a heart beat of my own
           C (x32010@1)and then I filled his veins
         F (133211@1)with the blood I had

Dm (xx0231@1)       GTil (320003@1)his blo-oh-oh-oh-od (x 3)
       C (x32010@1)Em (022000@1)name="chord_x02210@1">Am F (133211@1)C (x32010@1)name="chord_022000@1">Em Am (x02210@1)name="chord_320003@1">G

AmOh, (x02210@1)I'd build you up, 
    G (320003@1)                   F (133211@1)     (F G)
