Hmmm... I WOULD just spend it on a Bugatti Veyron...
But I'd tithe 10% and put $15,000 in a bank account or savings and get loads of interest, putting in more and more money in to raise that intrest... Spend a little to help pay off the house, put a bit into college savings, make an OK custom computer and probably spend the rest on game consoles and games.
Hmmmmmmmmmmmmmmmmmmmmm....... ..............
The Bugatti Veyron sounds more interesting.
