Heyy, I'm not a big Blink fan, but my friend just got a bass and was interested in learning this song. 
However, there were no real good tabs of it, and I tabbed it out for him. So I'm sharing my discovery with 
you guys...have fun kiddies.
Please visit my band website... www.ffotmusic.cjb.net. If you take the time to go there, 
I thank you alot! 
Please rate this tab, I'm not sure if it's 100% correct...PLEASE RATE!!!
AIM: UnsungZeroTSL for questions/comments.

To me, it sounds like Mark is hitting extra notes between the root notes
(Ab, E, B, Db)...if you don't feel comfortable playing the E and Eb portion of
the song, then you can just skip it...and even if I'm wrong, it's still better
to play and jazzes up the song a bit.


Bridge:
G|-------------------
D|-------------------
A|-22222222----------
E|---------00002222--   x8
Note: the bass is very low in this segment...listen carefully, and you'll hear Mark strumming
