can you smell potatoes?

McCain adverts that smell of freshly cooked jacket potatoes with the press of a button.

McCain are set to make commuters mouths water and the daily bus run ever more depressing with "sniff and smell" adverts. But only those in London, Nottingham, York, Glasgow and Manchester will be treated to the 3D adverts, which will dispense vouchers for the frozen pot at each push of the button.

The smellyverts are a part of a campaign is the biggest ad capaign by McCain since the infamous oven chip in 1979.

Is this what we can expect in the future? Not sure how I feel about smellyverts for a few things...
