Plain White T's - Stop Bass

The intro is really hard to do.  I've seen these guys play a few times and everytime i cant quite catch how the intro is done but i know the rest is 100% correct ive seen it played many times.

VERSE
-------
G:----------------
D:----------------  (Play this a few times on each verse. There are different 
A:---------222-555   variations as the verse goes on. This is also the part for 
E:-333-555--------   the guitar solo)

Chorus
------
G:---------------------
D:---------------------  (Stays the same through out every chorus)
A:---------------------
E:-777777-333333-555555

Thats jsut about it. I learned this song about a day after i got the PWT stop sampler cd at the past warped tour)
