From Amusing Planet:
Every year, thousands of Scots gather for the Up Helly Aa fire festival in Lerwick on the Scottish Shetland Islands to pay homage to the country's Viking heritage. The day long celebration consist of costumed parties and culminates in a torchlight parade and the burning of a Viking long boat. There are also plenty of kilts, marches to brass band music, even a new beer found only at the event.
At least 5,000 spectators come to watch more than 1,000 torch carrying "Vikings", in silver plates and helmets, with heavy axes and shields, march the galley around the town. Some enact the roles of famous "Jarls" from the local saga, the Orkneyinga. At the climax, all the Vikings throw their flaming torches into the galley. The whole crowd sings Viking songs and the party continues long after the last flames have died away.
