By my definition of fun and worth seeing(I thought the priceless credit card stuff was usually quite dull), those beer commercials where all the guys were going Wazaaaaaaaaaaa into the phone and making silly noises back at each other. Those cracked everybody up and were VERY different from any commercial I had ever seen. It made those guys stars and was really infectious; people were doing that to each other when speaking all the time for quite a while after.

That something could be so different and yet still so loved by almost everybody was pretty unique.

Aside from that, I'd pick the Got Milk? campaign. Great commercials, great milk moustache print ads, everybody knew it.

Honorable mention to the Jack in the Box commercials that turned Jack in the Box from a brand name that carried virtually no distinction whatsoever to one that had some fun in it. Some of the commercials were pretty good, especially the first one.
