C              Cmaj7               F
What do tigers dream of, when they take a little tiger snooze?
        C                Cmaj7            F
Do they dream of mauling zebras, or Halle Berry in her catwoman suit?
G                    Am                                            
Don't you worry your pretty stripped head 
            F                              C
we're gonna get you back to Tyson and your cozy tiger bed.
    G                         Am             
And then we're gonna find our bestfriend Doug 
    F                           C
and then we're gonna give him a bestfriend hug.
G     Am        F            C
Doug, Doug, Oh, Doug Douggie Douggie Doug Doug.
    C            Dm          Em           F
But if he's been murdered by crystal meth tweakers, 
     F          G           Cadd9
well then we're shit out of luck.
