This is tabbed like crap, but it is the correct way to play it (or atleast the intro). For the intro, ALL OTHER TABS THAT I HAVE FOUND ARE WRONG. Just play along with the rhythm of the song and you'll get it down.

Intro/Verse:

G|----------------
D|----------------
A|2--0--2-0--0----
E|----2--------0h2



Verse Riff 2 (played during spoken parts of the verse before chorus)
g|--------------------------|
d|-4-2----------------------|
a|-----5-4--2-0---2-0-0-----|
e|--------------2-------0h2-|


Chorus
g|-------------------------|
d|-------------------------|
a|-2-2-2-------0-0-0-------|
e|-------2-2-2-------0-0-0-|

Chorus Part 2 (Well Here We Go Again....)
g|-----------------------------------------------------------------|
d|-----------------------------------------------------------------|
a|-----------------0-0-0-0-0-0-0-0-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-|
e|-3-3-3-3-3-3-3-3-------------------------------------------------|

g|-------------------------------------------------------------------------|
d|-------------------------------------------------------------------------|
a|-----------------0-0-0-0-0-0-0-0-----------------------------------------|
e|-3-3-3-3-3-3-3-3-----------------0-0-0-0-0-0-0-0-12-12-12-12-12-12-12-12-|



If you ask me, this is really accurate.
