Hey, don't laugh at him just because he's fat
(you're not the fat man? I'm the fat man)
(I'm the fat man) (you're the fat man)
(who's the fat man?) (I'm the fat man)
(he's the fat man) (I am the fat man)
(I thought I was the fat man)

Well, let's get this straight, now who's the fat man?
(I'm the fat man)
(I've been the fat man around here)
(wait, buddy, there's no room in this studio for both of us)
(I'm the fat man) (I'm the fat man)

Well, you both look pretty fat to me
(who's fat?)
(the fat man? the fat man)
