What a tune! I based the tab on the way this guy, T-Bone, plays it. 
The chords don't fit too well with the recorded version but I think
you'll agree that it captures all the fun of the original 
and if you can sing it half as well as him then you're doing alright) ;)

Oh, you're a rich, bitch girl (rich girl) yeah
Say money, but it won't get you too far
