When someone is exaggerating, why are they called A fisherman?
This comes from the tendency for a fisherman to exaggerate the size of the fish that he caught, or the fish that he almost caught.
Is there a known origin for this saying? Can you provide examples of when this saying has been used historically?
The saying a fisherman is often used to describe someone who is prone to exaggeration, and the origin of this saying can be traced back to the tendency for fishermen to exaggerate their catches or near-misses.

Fishermen are known for telling tall tales about the fish that got away or the ones they caught that were much bigger than they actually were. This is because fishing is a sport that involves a lot of luck and chance, and so exaggerating their catches is a way for fishermen to show off their skills and impress others.

The phrase a fisherman as a descriptor for an exaggerator has been in use for many years. It was first recorded in print in the early 1800s, with one example being a quote from the British author Robert Southey in 1829, who wrote, There is nothing like a fisherman's story for exaggeration.

In American literature, the use of the phrase can be traced back to Mark Twain, who used it in his 1876 novel The Adventures of Tom Sawyer. In the book, the character Tom Sawyer tells a story about catching a fish that was as big as a man, leading his friends to call him a fisherman.

The saying has since become a common phrase used to describe anyone who exaggerates or tells tall tales, regardless of whether or not they have anything to do with fishing.
