Do you know the origins of the expression, "Cock and bull story?"
Most people know it means a fabricated or highly exaggerated story intended to deceive. (I always thought it referred to an argument between a rooster and a bull.)
But no! This is the origin of the phrase:
It is a corruption of a "concocted and bully story". Bully is the Danish bullen, or exaggerated. Therefore, it stands to reason that a cock and bull story is a made up, exaggerated story.
