Monkey Buffet Festival, Thailand
On the very last Sunday of November, if you find yourself in Lopburi, Thailand, you can attend this strange and wonderful festival. In an ancient temple, an impressive feast is held for the local macaque monkeys（猕猴）.After the ceremony，the furry guests of honor begin to enter the temple. Sheets are then pulled from tables and towers which feature a bright and dazzling pile of fruits, vegetables, candies, and even ice cream! Just come to watch these precious animals feed on the food happily. Actually it sounds like a party to us too.
El Colacho, Spain
This strange festival actually dates all the way back to 1620. Babies that are under 1 year of age are all welcome to participate. These babies are laid out on mattresses（褥垫）in the middle of the procession（队伍）route. Men dressed as devils will then wait for the beat of a drum to signal they should begin. Holding whips, they make their way around the route, jumping over each mattress with the baby on it. Locals feel that the event will bring their children health, luck, and guard them against evil spirits.
Cheese Rolling Festival, England
When it was first started, locals of the English town of Brock worth, Gloucestershire would gather at Cooper's Hill. Nowadays, this festival attracts competitors from all over the world every May. From the very top, a 3-4 kg wheel of cheese is sent rolling down the hill. Participants take off after it, trying to catch the speeding cheese wheel. If nobody manages to catch the rolling cheese, the first person to cross the finish line would be the winner. The prize is the wheel of cheese, of course. The trip after the cheese is so difficult that doctors wait at the bottom to provide first aid to unlucky participants in need.
