A priest was complaining to one of his colleagues that he had left his bicycle outside the church and it had been stolen. In such a remote parish, it could only been one of his own flock. Who would have expected such an act of betrayal?

The other priest suggested that he should take the Ten Commandments as the subject of his next sermon. When he reached "Thou shalt not steal", he should stop and stare at each member of the congregation, looking deep into their souls. The guilt would be sure to be too much for the evil doer and the bicycle would, more than likely, turn up again outside the church as if by magic.

Two weeks later, they met up again and the second priest asked what had been the result. "Ah well," said the first priest, "I was writing the sermon and when I got to 'Thou shalt not commit adultery', I remembered where I'd left my bike."
