ok i'm sure this is right. the first riff goes:
 e/----------------------------------------------
 B/-----1-----0-----1-----0---1-----0-----1-----0
 G/----------------------------------------------       PLAY 3 TIMES
 D/----------------------------------------------
 E/----------------------------------------------

 after 3 times u play:
 e/------------------
 B/-----1-----3-----1
 G/------------------
 D/------------------      YOU PLAY THIS WHOLE THING TWICE AT A TIME
 A/------------------       in the beginning and after each chorus)
 E/------------------


  There is only one more part to the song and it's played with
  the riff, during the chorus, and in the bridge the are only
  strummed once. The verses are only played with the bass.
  These are the chords: C-G-E-F


  Anyway, that's it. It's a pretty east song. Once you lisen to it
