Which idea did you like the best and why?

Guerilla marketing means a promoting their things with time energy imagination and information. People rather have a try on things on their promotion rather than watch on television or such. My favourite guerilla marketing would be the one with people sliding down. It is fun, and faster than the escalator. In fact, it is rather unique and attracts more people to in, and it's not like they will be forgetting about it within seconds just like a commercial.
