Ay, maybe they'll start making goofy hairbands with the numbers on top instead. I can just imagine the 1s getting broken off and stabbing people in the eye....

At some point I heard people referring to 2000s as the Aughts. But I don't think it has entirely caught on. We could be snooty and call it the fin de siècle though that doesn't really refer to the decade. Wait another twenty years and maybe there'll be a sitcom called "That '00s Show", and we'll finally have figured it out.
