I'm pretty sure I'm fatter than fat man. Can my title say fatter-er man or something like that?
I have met Fatman, and I wouldn't be surprised. Of course, by the time I met him, he was taking back control of his life, and his girth. And the self-depreciation of his self-imposed screenname was genuine, unlike your belated attempts to fit in.
BTW: For a guy who rarely drinks, he has better taste in booze than you.
