What is your favorite commercial?

Wish I could help out on this discussion BUT I do not watch enough T.V. to be able to really compare commercials, but with that being said I do remember the last one I seen that I liked and thought it was really funny..It was either a Sprint, or T-Mobile commercial where the two guys are talking about the others girlfriend and it plays a song by Cheap Trick I think. Anyways the one guy is telling the other that he has no relations with his girlfriend and about that time the girl calls and it plays a song about I want you to want me..Ha..
