A man was walking one night when he saw a church, brightly lit, with a service going on inside. The doors were open, so he went in and began praying. But when he looked, there was something wrong with the faces of the priest and the clergy.

‘Something unclean here,’ he thought. He began backing towards the doors. They were unclean spirits. They spotted the man and rushed out of the church after him.

The spirits looked: there was not a single footprint leading back out of the church, only footprints going in. They searched and searched, then gave up.
