Its all done with tongue in cheek and with that brilliantly sarcastic yet witty voice. The opening video is magnificent, with wonderfully written lines like: "that utterly senseless and irresponsible act was to illustrate a point, that a much loved brand is being beaten from existence." and "Even local schools are helping out, St Enids has introduced child labour to the curriculum." The 'can fist' symbol is a brilliant bit of hookery.
Games such as 'click as many times as you like, the more you click the more you help us'; in which cans constantly appear as you click; are brilliantly done.
The soprano voice for titles, the desktop images with 'Rainforests can grow back, save tango', the Tangometer sitting at 'Up the creek'; its all produced and thought out so well that it actually does remind you of the brilliance of their past, and how sad it would be to let it go.
So people. Can Fist. Save tango, if not for the drink, for the ads.
