What is the meaning of this?

So I thought that there was supposed to be this big Dr. Pepper add campaign with famous "doctors" telling us to drink Dr. Pepper all slow like, to bring out the flavor. I was promised Dr. Frasier Crane! But I have not seen hide nor hair of him on the TV. I mean excpet for the 4 times a day his show is on in reruns. But whatever, my point is, they start the add campaign out with Dr. J, fine, I can accept that. But where the hell is Dr. Crane? In these terrifying economic times I need a name I can trust telling me what products to buy and at what pace to drink them. He's a doctor for God's sake. Anyway, someone get to the bottom of this for me, please. I would but I don't think I could handle it very calmly right now.
