Meaning: Go earn money
This one has many interpretations. Some believe it started in a tradition in Dunmow England where the Dunmow Flitch was given every four years to a couple who impressed the town through their strength of fidelity. The prize? A big ol’ side of bacon.
However most believe the term derives from a 1906 lightweight boxing title match with Joe Gans. Bacon was a slang term for your body (and by extension your livelihood or income) since the 1700s. Joe's mother told her son before the fight, “Joe the eyes of the world are on you. Everybody says you ought to win. Peter Jackson will tell me the news and you bring home the bacon.” This quote was published in The New York Times, and caught on, creating one of the tastiest expressions ever.
