Budweiser Commercial - Clydesdales Donkey

The boom factor would be becoming a Clydesdale instead of just being recognized as a donkey.  The creative strategy would that if you put your mind to it, you can be anything you want to be.  The persuasion aspect of this ad is that if you want to ride with the best of the best you need to be one of the best, which it is saying that Budweiser is the best, and to join the best you need to work for the best.
