Witty advertising

As Indians, we typically like to pride ourselves as an intensely " news concious" and as a generally "aware " bunch.So, whats the best way to check if you've zoned out and are off-track with the current affairs and generally relevant things? Check out the Amul Hoardings around the city which are constantly updated. They parody whatever it is which is " the flavor of the moment." They are subtle, witty, informative and an extremely effective way of advertising and really the clincher being the fact that they viewer is attributed to possess atleast some amount of inherent intelligence.
