Pistachios are one of nature's trickiest double edged swords. On the one hand, they are ever so tasty, but on the other hand, they lacerate your tongue. This isn't any sort of fun laceration that I'm talking about either, not that there really is such a thing unless you've got masochistic tendencies. Anyway, the point is, pistachios hurt your tongue if you eat too many. If I'd known then what I know now, I still would have eaten all those pistachios because, in a gains and losses kind of world, pistachios are so totally worth it.
