We buy one every once in a rare while (not even as high a rate as one per year), for the "what if" game. Yes, logically, it isn't going to happen. But, it has provided us with a lot of fun playing "what if". Much more enjoyment out of a couple of bucks than, say, a movie, or a soda out to eat (neither of which we do anyway though). We do always participate in the work lottery pool; I can think of 3 in the 15 years I've been with the company, when it gets really outrageously high, because I'm not going to be the one person left in the building. :) But, we definitely view it as a form of entertainment, and an opportunity to evaluate our priorities. What things should we be working towards anyway that we could make realistic instead of viewing as a dream or someday, that sort of thing.
