Jim crazy or not?

This picture act as a reminder to me, that Jim is so supersites. It make me wonder just how gullible he can be, however he was right about the rain. Although telling the weather based on animal behavior isn't hard, my family and I do a lot of things by the signs of nature. Although we don't believe witches possesses our bodies and fly around the world, that's just crazy. I don't even want to say what I think the bank he described, and how he spent his money. After get that far into the book I think Jim is just another nut.
