Winning Mega Millions numbers announced Updated at 11:18 p.m. (CBS/AP) ATLANTA - The drawing for what could be the single biggest lottery payout the world has ever seen is finally here. The numbers drawn Friday night in Atlanta were 2-4-23-38-46, Mega Ball 23. A $640 million jackpot is up for grabs. Taken as a lump sum, it would amount to $462 million - or about $347 million after federal tax withholding. It will be a couple of hours for details on possible winners come out. Before Friday night's drawing, lottery ticket lines swelled as the record Mega Millions jackpot grew to $640 million, thanks greatly to players who opened their wallets despite long odds of success. Across the country, Americans plunked down an estimated $1.5 billion on the longest of long shots: an infinitesimally small chance to win what could end up being the single biggest lottery payout the world has ever seen. A cafe worker in Arizona reported selling $2,600 worth of tickets to one buyer, while a retired soldier in Wisconsin doubled his regular weekly ticket spending to $55. But each would have to put down millions more to guarantee winning what could be the biggest single lotto payout in the world. "I feel like a fool throwing that kind of money away," said Jesse Carter, who spent the $55 and donated the last two tickets he bought at a Milwaukee store Friday to a charity. Laura Horsley, who does communications and marketing for a trade association, bought $20 worth of Quick Pick tickets at a downtown Washington, D.C., liquor store Friday. But Horsley, who said she won't buy a lottery ticket unless the jackpot tops $100 million, remained realistic. Thousands of players -- who converged on convenience stores in 42 states and Washington, D.C., where Mega Millions tickets are sold -- agreed. Kelly Cripe, a spokeswoman for the Texas Lottery Commission, said that as of Tuesday, nationwide sales for the Mega Millions drawing totaled more than $839 million. Officials projected an additional $618.5 million in sales ahead of Friday's drawing, however, for a projected total sales figure of more than $1.46 billion. "This is unprecedented," Cripe said Friday by e-mail. Some Indiana players managed to get freebies, as Hoosier Lottery officials gave away one free Mega Millions ticket to each of the first 540 players at several outlets around the state Friday -- a plan announced before the jackpot grew by $100 million. In Indianapolis, college student Chris Stewart said he showed up at the lottery's headquarters at 6:30 a.m. to be first in a line. "I've never seen a jackpot like this before," said Stewart, who bought five additional tickets. If I won -- I mean wow! The lines were out the door at Rosie's Den cafe in the rural northwestern Arizona community of White Hills, 72 miles southeast of Las Vegas and one of the closest points to Nevada -- which doesn't offer Mega Millions -- for buyers to get in the game. Better long-shot chances, of course. For David Kramer, a lawyer in Lincoln, Neb., buying his Mega Millions ticket wasn't about "the realistic opportunity to win." In Armen Keteyian's report for "CBS Evening News," the revenue from that jackpot pie is divided in three ways: About 60 percent goes to prize winners; 15 percent to retailers, marketing and operations; and 25 percent, or about $14 billion, goes back to the states for government services. And while states earmark that money for education programs, state lotteries covered only a fraction of state education spending," according to a CBS News investigation. Lottery officials are happy to have Friday's record Mega Millions jackpot fueling ticket sales, but even they caution against overspending. And what happens if you win? CBS MoneyWatch's Jill Schlesinger has some recommendations -- among them 1) Read the rules on the back of the lottery ticket and the lottery web site; 2) Assemble a team that would include interviewing attorneys and financial advisors; and 3) Allow yourself to spend a little money, but don't go crazy.
