An archaeologist was digging in the Negev Desert in Israel and came upon a casket containing a mummy.  After examining it, he called the curator of a prestigious natural-history museum.

"I've just discovered a 3,000 year-old mummy of a man who died of heart failure!" the excited scientist exclaimed.

To which the curator replied, "Bring him in.  We'll check it out."

A week later, the amazed curator called the archaeologist.  "You were right about the mummy's age and cause of death.  How in the world did you know?"

"Easy.  There was a piece of paper in his hand that said, '10,000 Shekels on Goliath'."
