Hail and Hardy

I have spent a disproportionate amount of time thinking about Hale and Hearty Soups.  Hale? Hearty?  A proper noun and an adjective? Did Thomas Hale and William Hearty make soup together as pilgrim boys?  

Research reveals: “Hale & Hearty is a phrase from Shakespeare that means ‘healthy and well nourished’ (www.haleandhearty.com).  It is used in Henry IV (www.google.com).  People have found myriad ways to insert hale and hearty into stories about parents growing old, personal accounts of recovering from common colds, and granola cereal (general observation).  Also, “hale” is first defined as “free from disease or infirmity”, which I always appreciate about my soup.  

Essential question:  Why are you quoting Shakespeare to sell soup?
