http://playspent.org/This great little site simulates what a month on your last 1,000 bucks is like. You start with 1,000, and you have to make it through 30 days without going bankrupt. You have to deal with stuff like, picking a job, picking where to live, dealing with problems as they come, paying bills, buying groceries.
We had to do it in my Personal finance class, and I suggest you all do it legit the first time through, at least.
My record for finishing the month was around... $358 or so. Post how much you finish with!
