Bringing home the bacon has been a term used through time to acknowledge working and earning a pay check. It has been used less and less these days, especially because of animal rights activists, but you know your parents and/or grandparents used this term every week.
The phrase “Bring home the bacon” or Flitch Day actually comes from the 12th century when a church in Dunmow, England offered a half a pig (or Flitch) to any married couple who could prove to a mock court with a jury of bachelors and maidens, that they have ‘not wished themselves unwed’ or been unfaithful in their marriage.
The details are not certain, but references to it go back to 1104. It has been a regular civic event in Dunmow since 1855. Now held every 4 years, and frequently televised.
