"Me too" is also the name of an advertising technique where the ad displays attractive and desirable scenes, and implies that whoever is watching the ad will also achieve such pleasant results if s/he uses the product being advertised.

A typical example is a Claritin commercial. You see some people, with their family, running around in a big, pure green field, and a pure blue sky, having fun, smiling, and flying kites. Looks good? Especially to people with allergies? You bet. They say "Me too!" and they run out and buy Claritin so that they too, can experience this wonderful scene.

Ok, so it's not QUITE like that, but that's what this technique's basic theory is. Soda commercials do this a lot too. Remember the people all dancing and having fun in those Dr. Pepper ads? Or the Life Tastes Good Coke ads? You see these all over the place. Not just on TV, either. Beer and cigarette ads tend to favor this style in print publications too. I'm not entirely sure, but I think it might be the most common format for advertisements, all in total.
