This song is by Hank Green of the vlogbrothers.  Hank explains how to play here
but I figured I would type it up for people who need to read it.  If you want to hear the
of the song I followed to do this (it's slightly different from the original in lyrics, 
etc.), visit this link: 
http://www.youtube.com/watch?v=1iymaxV6Osk&p=CEDC77FCC40730A4&playnext=1&index=21.

Capo 2nd fret
Standard tuning

Be aware of the strumming pattern.  Hank explains in the first video I linked to, but
is a quick explanation (for the intro):

G down
DD up down
CC up up
GG down up

Also, the chords followed by ! (the only chords followed by that are a few C's)
they are staccatos.

Without further ado, enjoy "Book Eight" from So Jokes!
