Microwaves in U.S. households
In 1978, only eight percent of U.S. households had microwave ovens. As of 2006 over 80 percent have them.

It is commonly understood that Paul Revere said "The british are coming, the british are coming."
However, Revere never said "The British are coming," this would have made no sense at the time since they considered themselves British.
Revere instead said, "The Regulars are coming out! The Regulars are coming out!" But, that doesn't have quite the same ring to it.
