How Old Is It?

An American on holidays in England visited the British Museum and was intrigued by a magnificent Egyptian mummy.

"How old is the exhibit?"he asked a guide.

"Four thousand years and three months,sir; said the guide.

"How can you be exact? about the age of a thing like that?" demanded the American.

"Well sir," replied the guide. "the gentleman who donated it to the Museum said it was four thousand years old, and that was exactly three months ago."
