As I was fixing my breakfast, I was reminded of a (possibly apocryphal) story about Bill Monroe, Father of Bluegrass.
Some years ago, Monroe and his band The Bluegrass Boys were on tour up north. At their hotel, breakfast was laid out buffet-style. Bill went first and after a few puzzled moments, turned to warn the group, "Boys, don't touch those doughnuts. They're hard and they're cold and they ain't a bit sweet."
