This song is originally played on a ukulele but a capo on the 6th fret of a
guitar is standard uke tuning with a bit more of a full bodied sound.

Verse 1:

      E
Im in trouble

I'm an addict

I'm addicted to this girl
            A
Shes got my heart tied in a knot

And my stomach in a whirl
         E
But even worse I can't stop calling her

She's all I want and more
       A                  B
I mean damn, whats not to adore?

          E
I've been playin' to much gee-tar

I've been listenin' to jazz
  A
I called so many times I think shes goin mad
         E
And that cellular-er will be the death of us
  A        B
I swear, I swear

*Here he mutes the strings and strums the rythm is 1...1,2..1,2,3 The rythm is the same 
the chorus

And oh oh oh oh oh oh oh
A
Ooooh Oooooh

Chorus:
                                 E
I'm running my mouth just like I got her
             A     B
But I surely don't

Because shes so-o-o-o-o-o-o
A
ROCK AND ROLL!
              E
And out of my league
                 A
Is she out of my league?
         B
Lets hope not


The rest of the song is the same. This is 100% correct and tabbed by ear I've played it 
with the song many many times.
