Traditionally, you can run around a church widdershins three times to summon Satan. It is not clear whether this should be amended to clockwise in the Southern Hemisphere. (Addendum: I just checked 'widdershins' - it seems that the definition of widdershins is different in the southern hemisphere anyway. I still have no idea whether clockwise or anticlockwise is right in the antipodes.)

A good recipe for the 'reject God' version can be found in Marlowe's Doctor Faustus. Noded here.
