It was a JAIL - right?"
There were no bars in the room where Joey was kept, and where he and the others were boozin' it up. Guess Joe's seer-stone didn't tell him that karma was out to git him. Poor Joe; what a schlub. He shouldn't have gone against Christianity by creating his cult; shouldn't have had his daliances with other men's wives and shouldn't have ordered the Nauvoo Printing Press to be destroyed.
Karma is tough stuff to deal with.
