monetary policy

I (and all the other TAs) got a $250 in this month's paycheck for no reason. I suspect the grad student union has something to do with it. I don't know what to spend it on. I am so used to being miserly and poor I can't bring myself to buy anything big, or even medium. Part of it is a time issue - I could buy games, but right now I have no time to play them. And then Christmas is starting to get close so I'm not supposed to buy stuff for myself anyway. My trusty TI-30x Solar calculator is dying, so I put in a bid on eBay for three more at $1.99 each. I'm a big spender.
