As viral and guerrilla marketing goes, the whole concept is to think outside of the box. Way out of the box. That's why few brands have success with these types of ads because they're either afraid that what they're doing is not in tune with their brand's image or they're simply worried that what they do won't go over well with the public.

But there are some brands that don't really do much in the way of worrying about what people will do when they do something completely out of character. And this is precisely what makes them stand out from the rest. Take this new viral campaign from Volkswagen->ke94 for instance.

Bringing back those people from VW's Fun Theory responsible for those viral videos that made the Web last year, Volkswagen's at it again, doing a little subway slide experiment at the Alexanderplatz subway station where they built a slide to entice people to try living - or, in this case, sliding - in the fast lane once in a while. And as is the case when you slide on the stairs going down to a subway station, you're going to have to give it a go for yourself, as did a lot of people in the video ranging from young little tykes to even senior citizens, proving that everybody's entitled to a little fun in the fast lane once in a while.
