This ad is genius by Guiness. As most who have had a Guiness know, it takes a while for the foam in Guiness to go down. As a former bartender, I know it has something to do with the nitrogen they put into it when it's on tap...but anyway... Well, that means that when you order a Guiness, you know that it is going to take a couple minutes before it is served. You can't expect it to be out with the Miller Lite, Budweiser, or anything else....You have to be patient.

Through the reverse evolution in this advertisement, it conveys that waiting is worth it when it comes to Guiness. You may have to wait a while to get the beer, but you won't regret it.

I also like that the tadpole makes a "Yuck" noise when he tastes the water.
