Thai people believe that keeping monkeys happy brings good luck. So every year there's a day on which
they have a special treat for monkeys called the Annual Monkey Feast. Hundreds of monkeys come from the
mountains to "sit at" long buffet tables which are piled high with bananas, peanuts, wat.mp3elons and cabbage.
    Monkeys will be monkeys. So they fool around and fights break out. But nobody seems to care. Neither do
the monkeys. They just stare back at the crowds of people who turn out to watch them. Then they continue to
monkey around and have a good time.
