Dunmow Flitch Trials
Couples who can prove they haven't argued for a year and a day — or alternatively, that they've argued but always reconciled within 24 hours — can claim a side of bacon (a 'flitch'). Candidates are 'tried' by a jury of six maidens and six bachelors. The trial has been held since 1104. Only 300 flitches have ever been awarded.

The Lerwick Up Helly Aa is Europe's largest fire festival. A thousand-strong torchlit procession of Vikings in full regalia marches through Shetland's capital before hurling their torches into a replica longship, burning it to ashes. The night ends with ceilidh dancing until dawn. It's dark, it's loud, it smells of paraffin.
fireTar Barrel Rolling
Locals set fire to full-sized tar barrels and carry them through the narrow streets of Ottery St Mary on their shoulders, before rolling them down the hill. Participants wear leather gloves and asbestos aprons. Children get their own smaller barrels. The town smells of burning tar for days.
