My favourite is advert for washing machine, brand Ariston. I saw it on English TV about one year ago. Comercial is about a little boy who observ what is happening inside machine and he see plenty of colorful fish, water plants and coral-reef. this is amazing view. In background we hear slow melody and for time to time sensual women's voice just like mermaid.
The boy is surprised and can't believe what he saw. At the end of this advert speaker told that ariston is deeply different from others.
