Have you every seen one? a blue buffalo? I didn't. But that's what imagination gives us - where a buffalo can be blue, a cow can climb a tree, a man can survive in outer space or deep sea, without oxygen. The list is limited only by your imagination. btw, you can see the Rx more clearly on this one. Funny, that ever a doctor would prescribe someone to eat a blue buffalo calf, as a cure for all maladies.
