Hey, you never know, right? At $540 million, the Mega Millions jackpot has reached an all-time high — setting a world record for any lottery and enticing even snooty naysayers to try their dauntingly terrible odds. The jackpot soared after Tuesday's drawing — which featured a $363 million prize — failed to produce a winner. The gigantic haul could continue to rise before Friday's drawing as more people throw their money into the pot. Here, a numerical guide to the contest that is driving the nation into a frenzy:
