My best one and my last was in New Guinea a long time ago when me and my mate working on one of the missionary stations in the Highlands had a few to many and decided it would be a good idea to do laps of the local Church, whilst in service on Postie Bikes.
However I, whilst undertaking this exciting venture ran straight into a deep culvert and went straight over the handle bars.
My mate told me later it was such a graceful flight through the air, however due to the fact that I was half cut no serious injuries occurred
