Lots of outside work, depending on locale. Lawn mowing (depending on the type of alcoholic. Best not to contribute to lost fingers or toes), ditch digging, etc.
Dumpster diving (if it's still worth while, which it might not be).[1] If you're serious about it, it's not really any less of a job than those American Pickers guys.[2]
There's lots of jobs out there, especially if you widen your criteria for "job".
1: I had an interesting run-in with a homeless man at a taco truck almost two decades ago. He was in clean clothes, had a bike with a trailer, and was trying to sell a 49ers jacket. My friends and I started talking to him and he explained that he found a few of the jackets in a dumpster behind one of the big sports stores around, and had a few other things to sell too. He explained that he and a few friends actually had a fairly nice camp (carpeted areas, make-shift shower with water in the day through solar of some sort, DVD player with TV hooked up to solar trickle cell). He camped a little outside the stalled development of a local apartment complex, where they had an agreement with the developers that they could stay there and they would keep people from squatting in the partially completed complex so it didn't sustain damage. He said he was on disability from the military, and liked living outdoors, but would probably rent an apartment for the winter with his girlfriend and friend. Honestly, I left the interaction feeling a little envious of his freedom.
