Shampoo brand Timotei has launched an advergame in Spain in which blondes "fight" against dark hair women. The game is called "Rubias contra Morenas" with the subtitle "Defend your color".
You pick a girl and then you're challenged to throw (yes, throw!) your "enemy" as far as you can. If you register before playing you can even win some bottles of shampoo. I don't think I have to add I like the idea of a brand giving away its own products to have people test them.
