A grandmother from Australia has become "the world's loudest screamer" in a shouting contest. Mr. Dell Jensen screamed her way to victory in the "world Cooee Championships" in Queensland, Australia, recently -- outshouting 143 other men and women contenders.

SYNOPSIS: One of the early favourites showed the best way to scream. Mrs. Joan Dobby was last year's winner.

The quality and volume of each scream was measured on special recording devices, adding a touch of modern technology to a contest which had its origins in the Australian outback. Scouts on expeditions would keep in touch with base camps miles away by screaming loudly in the "cooee" manner. Today, it's just for fun, lots of beer to cool the tonsils, and a thousand Australian dollars worth of prizes.

And it's Mrs. Jensen screaming to her title. While she screamed, others took part in a beer guzzling contest.
