I never quite got why that was deemed so funny, I mean I got it, but...

An advert that won plaudits but is mostly remembered not for the product it was supposidly advertsing but what happend in it. Therefore IMHO as a piece of advertising it belongs in fail-land. A prime example of an advertsing agency dissapearing right up its own backside to produce admittidly a stunning piece of film but still something that has no relevance.
