I read a story where a delivery guy got two addresses mixes up, a fattie suddenly had a meal for 6 (instead of the usual 3-4) and ate the whole, fucking, thing. I think it's from a "What's the fattest thing you've done" collection, including one where someone at a cake before a meal, ate more. Then decided it would be a good idea to eat the rest of the cake and buy a new one and eat a slice from the second cake to make it look like they didn't eat that much. Then proceeds to throw-up after dinner.
