You don't have to feed fatty.
Not to be too crass, but let's be realistic, being a hobo means never having to buy your child three Double Quarter Pounder Extra Value Meals. And, of course, you'll never have to carry him upstairs to bed when he falls asleep in his bowl of gravy. Being a hobo inherently brings plenty of problems along with it, but at least back problems aren't one of them. (That is, back problems that come from carrying a large child upstairs, because, for a hobo, "there is no upstairs, there." People say that you'll never see a fat hobo, but that's not true. Some fat people become hobos, but hobos rarely ever become fat. Nobody overindulges on dumplings or biscuit-halves. Well, nobody except Biscuit Thompson, who was said to be the "biscuit-eatingest s.o.b. to ever set foot between the rails". Although, a cursory Google search of "Biscuit Thompson" only turns up a "Thompson Biscuit Company"...wait a second...you don't think...?
