The first instance of the term is difficult to trace, as it was a common reference throughout the centuries, most notably in King Henry V by Shakespeare, where he states “Therefore, my lords, omit no happy hour that may be given furtherance to our expedition.” As a reference to a particular time of entertainment, however, it can be traced to a much more specific date, in 1913 it originated from the United States Navy. It took only the length of World War I for the term Happy Hour to refer to all periods of indulgence, including smoking, wrestling, boxing, music, movies, and dancing. As a reference to a point of drinking, however, it made its appearance during the prohibition, the term “Happy Hour” referred to that time spent at a speakeasy before retiring to restaurants no longer able to serve alcohol. I'd be happy if it would stop raining for an hour
I thought the snowflake Brigade had them banned, used to enjoy a good few drinks during a good old happy session.
