In response to Maria's entry today I argue that the cow on the Olympic Milk commercials IS a blue cow. The whole campaign is about them trying to get you to identify with the cow logo on the milk carton. So the milk carton is white and I'm betting blue is the only colour ink they use. In actuality it's a clear cow outlined in blue with some blue spots. As blue is the only colour on there I think it's fair to call her the 'little blue cow'. I guess on the commercials they fill her in with white so as not to freak people out. Think of the commercial - if you could see other runners/swimmers etc, or the audience thru the cow , you probably wouldn't get a craving for milk. Maybe water if anything.
