Ringtone Market More Than Just Hot Air?

I still can't figure out if the ringtone market is just a fad, but it seems that plenty of young people have no problem spending plenty of money on custom ringtones. The most popular new ringtone? The sound of a certain... bodily function. That's right, young boys are now using their mobile phones as remote "whoopee cushions". Just plant your mobile phone under someone's chair, and then have someone call your number. The technology may change, but the jokes stay the same.
