I bought some shortbread of the kind the stores sell in the produce section next to the strawberries along with canned whipped cream. It's very similar to Twinkies material. I put it on top of the fridge and forgot about it. A month or so later I went to throw it out, expecting it to be moldy, but, nope. Looked as fresh as the day I bought it. Another month went by and I looked at it again. This was rather frightening but I left it there. After the third month I shrugged and put it in the freezer for the next time strawberries are in season. I'm really kind of afraid to eat it, though.
