I didn't count the GTA one as a Superbowl ad because it's been playing at my local theaters for a few months now. It would definitely be my favorite if it counted.
The FedEx moon one and the Bud Light hitchhiker one. I also liked the Doritos checkout one because the cum reference was a rather risque afterthought. The Robert Goulet commercial wins this year's WTF?!? factor. Does Coke actually have anything to do with black history month?
