I would cut my hours at work. I think I'd get bored sitting at home all the time and I really do like my job, but if I didn't have to work for a living, I wouldn't work as much. I think Mr. Bottlecaps would like to quit his job too - although he likes his job too, I think he'd rather be able to stay at home and play video games! :-P
I'd love to travel more, see more of the world, just for leisure. How nice it would be to be able to go places and do things without money being an object!
Oh, and I'd buy Mr. Bottlecaps a Bugatti Veyron (it's his favorite car), because why not? :-P
