Bored with cockfighting?

Try goat sumo.

Goat sumo involves putting two goats into a ring with a radius of about 6 meters and then setting them against each other as they butt horns, stand on their hind legs and attack each other.

Each bout can last for up to 15 minutes unless one of the goats runs away before that time. In the event both goats remain in the ring for the duration, the animal that has made the most hits with its horns is declared the winner. [MDN]
