You are given a a million dollars if you can spend it in one day. The transaction has to be finished that day, so no houses or similar. What do you buy?
Is this a "Brewster's Millions" scenario, where it has to be wasted, or do you just have to buy a bunch of crap?
Also, I'm presuming you aren't counting time for the check/etc to clear. Otherwise, very few of us could ever even conceivably make that level of transaction.
