Duval Guillaume has developed a new interactive campaign for Carlsberg beer that is built around a Facebook application, a TV commercial and a viral YouTube video. The basic premise is how loyal are your friends to you. Something that is kind of ironic when you think about all those friends you have on Facebook, that you barley know. The campaign centers around the a phone call in the middle of the night. Your best friend is in trouble. Would you go out and help him/her? You can experience all of the craziness here on Facebook.
