Amusing article... I actually just bought a handful of lottery tickets last night (hey, $40m jackpot, we don't screw around here in fl) but, no didn't win.
However, I was thinking about this stuff, and honestly I think if I were to win some ungodly sum of money, I'd do my best to keep it quiet. Or, more realistically, if I won $5 million - I'd probably go around telling people I won $500k. So I could still explain away a few ridiculous spending items - but not to the point where all my friends would be expecting me to buy them cars.
Having said all that though - it IS free money, and you only live once, so I do think I'd be inclined to go out and totally blow some of it, just for fun. Seriously, imagine how much fun you could have in a weekend with $30k burning a hole in your pocket..hahaha. But these stories of people squandering away millions in a matter of 2-3 years? That's retarded. The smart thing to do would be to buy your own house, if you were determined to help out family members or whatnot, BUY their houses (don't buy it _for_ them, buy it _from_ them and let them live in it), and then take a look at what you have left vs what you want to do with the rest of your life. Personally I think I'd be pretty happy with not paying for housing, and collecting a nice steady $25-35k a year of "Free money" for the rest of my life.
