Of course, Ms. Wanczyk, a 53-year-old health care worker, won’t see most of that money. She chose a lump-sum payment over an annuity, which lowers the total to $480.5 million. Then there are taxes: 25 percent to the federal government and 5 percent to her state, Massachusetts. That leaves her with about $336 million to take home.

Who cares? She’s almost as rich as Katy Perry and Matthew Perry combined.

She immediately quit her job of 32 years. “I’ve called and told them I will not be coming back,” she told reporters, to raucous laughter. Her first order of business is to “sit back and relax.”
