No. 4

In 1999, the NFL Replay System was put into place. Budweiser released a follow-up to show that not even Clydesdale football was safe from play reviews. In the new ad, the Clydesdales stand impatiently as a zebra looks into a replay monitor. The play he reviews keeps rewinding as the monitor clicks to show his multiple viewings, much to the dismay of the horses and two human spectators. One looks over to the other and says, 'This referee's a jackass,' leading the other to reply, 'No, I believe that's a zebra.'
