Talkin' bout a revolution

Can you think back to a time BEFORE sliced bread? Nope, neither can I and yet it wasn't all that long ago that we ate bread by tearing off hunks. Then, a light bulb went off in someone's head and sliced bread was the result. The concept of slicing bread was so ingeniously simple I'm sure the originator must have had a Eureka moment similar to Archimedes in his bath tub or to Isaac Newton when the apple fell on his head.
