Intro With guitar and bass carrys on through verse 1

She's a perfect 10, but she wears a 12
Baby keep a little 2 for me
She could be sweet 16, bustin' out of the seams
It's still love in the first degree

In the 2nd verese the 2nd guitar joins in with ther bass and 1st guitar but plays the 
instead

AWhen (x02220@1)he's at my gate, with a big fat 8
A (x02220@1)                             EYou (022100@1)wanna see the smile on my face
AAnd (x02220@1)even at my door, with a 4 4 4
A (x02220@1)                          EThere (022100@1)ain't no man can replace

Then comes the chorus In which the bass and 1st guitar join guitar 2 with chords!

A (x02220@1)                                      Bm'Cause (x24432@1)we love our love, in different sizes
              D (xx0232@1)                   AI (x02220@1)love her body, especially the lines
                                       BmTime (x24432@1)takes it's toll, but not on the eyes
              E (022100@1)             APromise (x02220@1)me this, take me tonight

In verse three & four, the 1st guitar and bass come back in with the funky intro riff 
the 2nd guitar plays chords again!!

AIf (x02220@1)he's extra large well I'm in charge
EI (022100@1)can work this thing on top
AIf (x02220@1)he's XXL well what the hell
EEvery (022100@1)penny don't fit the slot

AThe (x02220@1)anorexic chicks, the model 6
EThey (022100@1)don't hold no weight with me
AWell (x02220@1)8 or 9, well that's just fine
EBut (022100@1)I like to hold something I can see

Back to chorus, yep you guessed it all guitars play chords!

A (x02220@1)                                      Bm'Cause (x24432@1)we love our love, in different sizes
              D (xx0232@1)                   AI (x02220@1)love her body, especially the lines
                                       BmTime (x24432@1)takes it's toll, but not on the eyes
              E (022100@1)             APromise (x02220@1)me this, take me tonight

Final Verse played the same as 2, 3 & 4

AI've (x02220@1)bought a watch, to time your beauty
EBut (022100@1)I've had to fit a second hand
AI've (x02220@1)bought a calendar, and every month
EIs (022100@1)taken up by lover man

Chorus

A (x02220@1)                                      Bm'Cause (x24432@1)we love our love, in different sizes
              D (xx0232@1)                   AI (x02220@1)love her body, especially the lines
                                       BmTime (x24432@1)takes it's toll, but not on the eyes
              E (022100@1)             APromise (x02220@1)me this, take me tonight

Finally to end the song!!! Just strum the chords once in the verse!

A (x02220@1)                                      Bm'Cause (x24432@1)we love our love, in different sizes
              D (xx0232@1)                   AI (x02220@1)love her body, especially the lines
                                       BmTime (x24432@1)takes it's toll, but not on the eyes
              E (022100@1)             APromise (x02220@1)me this, take me tonight
