An Englishman was being shown the sights along the Potomac. "Here," remarked the American, "is where George Washington threw a dollar across the river."
"Well," replied the Englishman, "that is not very remarkable, for a dollar went much further in those days than it does now."
The American would not be worsted, so, after a short pause, he said: "But Washington accomplished a greater feat than that. He once chucked a sovereign across the Atlantic."
