A bean, a goat and a monk
It was said that coffee was discovered by a goat herder in Ethiopia in the 1500s. He saw his goats eating coffee cherries. Afterwards, he observed a change in their behavior. They gained a high amount of energy and they didn’t sleep at night. The herder shared his findings with local monks and then after they made a drink with coffee beans, they realized they could stay up all night and pray. Then, they spread the word to other Ethiopian monks and it reached across the civilized world. That's when that goat became "the greatest of all time"
