Tabbed by: Gangsta Pigeon
Tuning: Standard (EADGBe)

There are multiple ways to play this song, it all just depends on your preference. I'm 
to believe that this song is bar chords, and so, here they are.

A : 5-7-7-6-5-5---------------
D: 10-12-12-11-10-10  or  x-5-7-7-7-5- | 
G : 3-5-5-4-3-3---------------
C: 8-10-10-(b9)8-8   or  x-3-5-5-5-3---- | 

Intro and Chorus [and for verses 2 and 3 on piano in Complete Demos] (credit goes out to 
"behindmyglasses" from the bass tab):

e | --------------------------------- | 
B | --------------------------------- | 
G | --------------------------------- | 
D | --------------------------------- | 
A | -0-0-3-4-5-5-4-3-----1-2-3-3-2-1- | 
E | -----------------3-3------------- |      x2 for intro,

During the verse, nothing is played on guitar, but I shall include the bass tab (credit 
out to user "behindmyglasses" again, with a little bit of editing):
G | ------------------ | 
D | ------------------ | 
A | -0-0-5-5------3-3- | 
E | ---------3-3------ | 

That sums up what is being plucked, now I'll move onto the rest of the song. But please 
during the bridge from verse to chorus, there is a key change that I've yet to figure 
completely.

Verse 1:

I have little thing
It's probably just a fling
there's two girls I like a lot
I think they're really hot
I'm not sure if they know
how my love began to grow
it took a lot of time
right now it's solely mine

Verse 2:
(spoken) TO-DAY!
I drew a mural of the things I'd like to love
and where my heart subsides
is with two girls with great eyes

Bridge:

(spoken)
A    D      G                  C
     if they just give me a chance
    A                     D
I'd show them what they want
            G                 C
and teach them what they got
         A                    D                    G
and I'd tickle each and every one of their fancies
                  C
and I'd take the key to my heart
         A
and open it and let the love shine through

Chorus:
A             D        G             C
Mary Kate and Ashley I hope you understand
       A          D          G            C
that I love you a lot and I wanna be your man
            A  D
and I think
             G       C              A           D
that it'd be totally cool if I hung around your apartments
      G              C
and enrolled in your school

Verse 3:

            A   D
Mary Kate!
I saw you on TV
you dressed up like a bee
remind me of the time
how it's gone and it's gone and it's gone
it's sadness every day that passes without you
and I really wanna really wanna really wanna hold you both tight
and tell you you're mine but instead I sing

Chorus:
A             D        G             C
Mary Kate and Ashley I hope you understand
       A          D          G            C
that I love you a lot and I wanna be your man
            A  D
and I think
             G       C              A           D
that it'd be totally cool if I hung around your apartments
      G              C
and enrolled in your school

Complete Demo's only:
(spoken)

Yeah!

Chorus:
A             D        G             C
Mary Kate and Ashley I hope you understand
       A          D          G            C
that I love you a lot and I wanna be your man
            A  D
and I think
             G       C              A           D
that it'd be totally cool if I hung around your apartments
      G              C
and enrolled in your school


I know that life without you and you would be sad
I know it'd be bad

Chorus:
A             D        G             C
Mary Kate and Ashley I hope you understand
       A          D          G            C
that I love you a lot and I wanna be your man
            A  D
and I think
             G       C              A           D
that it'd be totally cool if I hung around your apartments
      G              C
and enrolled in your school

and enrolled in your school
