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

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

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'."
