Kids with mobiles do the darndest things

I loved this story when I read it this morning through MocoNews.net - a device that creates an annoying mosquito-like tone, which is only audible to under 20's (used as a "teen repellant" by adults for various reasons), is now being turned against the age-ist population. Teens have recorded the sound and are using it for ringtones and message alerts so that they can use their phones in class where the teacher can't hear it (and presumably in other scenarios where they don't want adults to know they're using their phones). Ha!

In the immortal words of all Scooby-Doo villains, "And I would've gotten away with it to0, if it weren't for those pesky kids!".
