When there were more woods, one man went from Lubník to Lanškroun. In Sázava Highlands near municipal border, there is woodlet where is necessary to get out of way of Green Jack. When this man did not see anybody, he felt like have a smoke. There was a trunk near the road. He started to chop a filler on it, he stuffed a pipe and then he arrived to Lanškroun and arranged what he needed. On his way back home, he met a guy who showed him wounded knee. That unknown person moved away. Than the man realized that the place on the trunk (where he chopped the fill) is a knee of the man that he met. It was nobody else than Green Jack.
