The Mega Millions has reached 586 million and could go even higher to a record.
To put things into perspective about the odds of winning:
You have a greater chance of being killed by a vending machine.
You have a greater chance of being hit by an asteroid.
You have a greater chance of finding a valuable diamond at the bottom of the ocean.
Or, as Jay Leno, put it in a monologue about the 1 in 259 million chance of winning: "That's about the same odds of Tony Romo completing a pass to a teammate in the fourth quarter."
