What are the odds?

While digging in the Negev Desert, an archaeologist came upon a casket containing a mummy. After a brief examination, he calls the curator of a prestigious natural history museum: "I have just discovered a 3,000 year-old mummy of a man who died of heart failure!" The curator tells the archeologist to bring the mummy in, they would check it out.

Sure enough, a week later, the amazed curator calls the archaeologist: "You were absolutely 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'."
