Did you know?

Eighteenth-century English admiral Edward Vernon reputedly earned the nickname "Old Grog" because he often wore a cloak made from grogram (a coarse, loosely woven fabric made of silk or silk blended with mohair or wool). In Old Grog's day, sailors in the Royal Navy were customarily given a daily ration of rum, but in 1740 the admiral, concerned about the health of his men, ordered that the rum should be diluted with water. The decision wasn't very popular with the sailors, who supposedly dubbed the mixture "grog" after Vernon. Today, "grog" can be used as a general term for any liquor, even undiluted, and someone who acts drunk or shaky can be called "groggy."
