Some of us already know how we'd spend the Powerball jackpot.

"I'm gonna call up all of my relatives, not letting them know I've won, tell 'em I need to borrow money and whoever lends me money -- that's who's going to get a bonus!"

But not everyone has a plan. Saturday's Powerball jackpot is now over a half billion dollars -- the third largest in U.S. history.

Seven-time lottery winner Richard Lustig says he's had fun with his winnings.

"I took the whole family on an Alaska cruise one time; another time I bought myself a Jag, which I drive. I've always wanted a Harley, so I went out and bought a Harley."

But Lustig says the most fun thing is staying rich.

"Most people that win these huge jackpots have never had that kind of money before in their lives and they don't know what to do. So, they run right out and buy fancy cars and houses and throw big parties and the next thing you know, they've used up most of that money."

Lustig says hire business advisors with reputable backgrounds and do what they say.
