Last night as I was stumbling into the house with my groceries, I found a tiger whisker on one of the door mats. Now, I have a pretty good collection of whiskers, but I generally keep them in a safe place, because they're a personal treasure. There are a few that I have in more exposed places, but none of those seem to be missing. It's definitely not the one I found on Sunday; that one was almost half black and this one only has a little black. As entertaining as it might be to speculate that a tiger came to visit while I was out and left it as a calling card, I think that's significantly less likely than being rescued from deep space 29 seconds after the Vogons space me. It's pretty certain that it's one I brought home earlier, but I can't fathom how it got there.
