here is a version of this song with out a capo (Justin doesn't use one 
when he plays this song) (I just added a clip of me playing this 
song if you want to take a listen)

intro: D, G, A, D, A
                    D
You got your million bucks
                         G
You got your flashy sports car
                    A      
You got your trophy girls 
                      D          A
Man you think you're a star

You got your teeth bleached 
You like to play the rich game
Yeah you think you're a cowboy
The new jesse james

chorus
                    D
But I could kick your ass
                 G
I could jack your jaw
                       A
Put you flat in the dirt boy
              D        A
Yeah id have a ball
                   D
So go ahead and act tough
                   G
Like your John Wayne's son
                   A
But things can change fast
             D           A
I can kick your ass


Tried to steal my girl
Better bring your big friends
Another one or two
Cause your gonna need them
You're a little to small
To be calling me names
Im bout to knock that smirky little grin
Right off of your face

I can kick your ass
I could jack your jaw
Put you flat in the dirt boy
Yeah id have a ball
So go ahead and act tough
Like your John Wayne's son
But things can change fast
I can kick your ass

:: Oh how about it boy::
outro D,G,A,D,A
 
Hope it is up to speck, this is my first one. comments/suggestions appreciated :-)
