kfc in the usa has a new tv-ad for this product. watch this video and see if you can hear the so called mosquito tone. this tone is so high-pitched that not all people can hear it, so check it out (by the way, i can hear it). this is also why a lot of teenagers use this tone as their ring-tone as especially older people can't hear it. the whole story to this promo-ad you'll find here.
