If you mysteriously had $200 that you didn't expect, and you felt compelled to use it to buy yourself a present, what would you buy?

This is not a hypothetical question. My dad sent me a check for $200 today, after taking back the digital camera he bought me for my birthday/Christmas, because Mark got one as well and we don't need two. I never expected to see the money, and here it is!

So the practical part of me knows I should just put it in my account for books and expenses and the money I always end up spending, even though I shouldn't. The other part, though, is screaming that this money is a PRESENT and should be spent as such.

What do you think?
