### Rosary and Two Martinis

A priest was sent to a very small church in the backwoods of Alaska. After a couple of years the Bishop decided to pay the priest a visit to see how he was doing. The priest said that it was a really lonely job and that he didn't think that he could have made it without his Rosary and two martinis each day. With that the priest said to the Bishop, "Would you like to have a martini with me?" The Bishop said, "Yes, that would be nice." The priest turned around and hollered toward the kitchen, "Rosary, would you fix us two martinis please?"

Armstrong's new system utilized a higher frequency band than was used by existing commercial radio transmitters. It eliminated all static and outside interference. Several hundred representatives of the radio industry were present. Armstrong presented the differences between the old and new methods with a series of sound-film recordings of the same program under the different conditions. FM was clear of the hissing, buzzing and crackling static noises of AM.«
