What is unusual about the discvery of coffee

Goats are notorius for their jumpy behaviour, but when goats jard Isaac Berham of Kaffa in Ethiopia took his goats out to graze among some bushes one day, he notices something unusual. His goats got more and more excited as they nibbled on some berries on the bushes. After a while they were really "high" and seemed to be performing a kind of goatish dance. Braham became rather curious about the berries that were firing up his herd and decided to try the m out himself. He chewed a few and he felt quite "good" after a few moments, He shaved his discovery with his people and soon the berries from 'Koffa were on many tables as coffee". Goats were of course to be strictly kept away form the previous bushes their discovery form then on.
