I found this episode high unlikely. It's strange that an old man who looks like an upstate farmer could set a scam like this. Maybe the Wolf of Wall Street could manage this, but not the late Geoffrey Lewis. There are too many things to plan and you have to connect the dots just in time. At the beginning it is shown how miserable is the underground life for the homeless: a tramp told Goren "It's getting too damn bright out here". Living in the tunnel turned him into a bat-like creature.
