New for fall: The Mosquito

In an attempt to foil bumbling professors yet again, a Welsh company has released a ringtone that most adults can't hear. Affectionately called "The Mosquito," it takes advantage of the fact that as we get older, our hearing starts to fail. Armed with one deaf ear, I was fairly certain that I wouldn't be able to hear it myself, but lo and behold, it seems that I'm not that old yet. So if my students attempt to employ The Mosquito, I'll retaliate with An Airhorn.
