To deal with all those Tivo and DVR users who fast forward through commercials, KFC has made an ad with a secret message that is "encoded such that it is only visible while the commercial is being
fast-forwarded watched in slow motion." KFC is also "offering a free sandwich to those who can regurgitate the hidden phrase." Of course you also will likely regurgitate the free sandwich too, but it’s still a good idea.
