I did see one of the commercials that used the "I like seal meat better" quote, which seems a bit strange. Not because he liked seal meat better, but Burger King's® conclusion was that people liked the Whopper® better. Seems like an equally plausible conclusion is that the Whopper® tastes more like Seal Meat® than the Big Mac® does.
It's almost like a company from Morocco coming to the US and asking what the best couscous® is. "Well, the first one tastes more like Macaroni and Cheese®."
(I like the Whopper® better (more specifically the Whopper Jr.®), but I eat the Big Mac® more often, so draw your conclusions as you will.)
