When pigs fly

Cincinnati flying pig

The idioms of this page are used to indicate that something is highly unlikely ever to happen, or that it will never happen. This phrase is thought to come from an old Scottish proverb.

An unofficial symbol of the city of Cincinnati, Ohio in the USA is a flying pig, partly a result of Cincinnati's associations with the pig trade during the 19th century.
