In Brazil, Mentos has recently launched a retro style viral campaign to promote its Power Kiss candies. A teaser video posted on Youtube promotes a series of lessons to be learned following the "Kamasutra do Beijo" (kiss Kamasutra) instructions.
The course can be purchased on VHS for just $3.50, and it comes with a pack of Mentos.
Unfortunately, despite the very good concept the Web experience is very disappointing. Don't waste your time visiting the website, the video "teaser" says it all...
