This is a very interesting variant on the theme in that this guy UNKNOWINGLY sells his soul to the Devil, the result of an off-hand figure of speech.  Very enjoyable episode.  Demon summoning.

This is one of the episodes whose recording include the contemporary news report.  I always listen to these to get updates on Watergate, and so forth.  This one had a blurb about local athlete Bruce Jenner.  Jenner, of course, will become very famous in two years when he wins the gold medal in the Olympic Decathlon.
