Why I carry a lot of keys:

Like many people, I carry a key ring full of keys. Now I know why. Not for the first time, a pair of pants developed a hole in the key ring pocket. I lost a nickel, three pennies and a quarter before I figured this out, but my key ring was much too large to fit through the hole! Is it a Murphy's law thing that of all my pockets, it's the one with the keys that gets the hole? I don't think so, it's more like cause and effect - those sharp keys poking away at the fabric.
