That, and there are different characters in the commercial that are the focal point. The Ford one is with Kermit, and the Pizza Hut one is with Ms. Piggy and Jessica Simpson. For the Ford one, you have Kermit walkin through the woods and finding a hybrid(personally, I think the car should've been green) and claiming that it now is easy being green. Whereas, the Pizza Hut ones focused on the "blond bombshells" Jessica Simpson and Ms Piggy. Personally, I would've liked to see more commercials like that from Pizza Hut, where Jessica and Ms Piggy are in full blown competition with each other. Kinda like, who is the better blond? But, they both are good in their own respect
