        A (x02220@1)              C#m/A            DDo (xx0232@1)they dream of mauling zebras, or Halle Berry in her catwoman suit?

Don't you worry your pretty striped head 
            D (xx0232@1)                            Awe're (x02220@1)gonna get you back to Tyson and your cozy tiger bed.
    E (022100@1)                        F#m (244222@1)           
And then we're gonna find our bestfriend Doug 
    D (xx0232@1)                         Aand (x02220@1)then we're gonna give him a bestfriend hug.
E (022100@1)   F#m (244222@1)     D (xx0232@1)         ADoug, (x02220@1)Doug, Oh, Doug Dougie Dougie Doug Doug.
    A (x02220@1)          Bm (x24432@1)        C#m (x13321@4)        DBut (xx0232@1)if he's been murdered by crystal meth tweakers, 
     D (xx0232@1)        E (022100@1)         Awell (x02220@1)then we're shit out of luck.

I like to arpeggiate the three chords on the part when he says "If he's been 
murdered by crystal meth", throw in some fills of 0-2-4 on the 1st string during 
the verse before you switch from the D chord to back to the A. it's fun to play, 
enjoy...
