I also believe that man’s continued domestication (if you care to use that silly euphemism) of dogs is motivated by fear: fear that dogs, left to evolve on their own, would, in fact, develop thumbs and smaller tongues, and therefore would be superior to men, who are slow and cumbersome, standing erect as they do. This is why dogs must live under the constant supervision of people.... From what Denny has told me about the government and its inner workings, it is my belief that this despicable plan was hatched in a back room of none other than the White House, probably by an evil adviser to a president of questionable moral and intellectual fortitude, and probably with the correct assessment—unfortunately, made from a position of paranoia rather than of spiritual insight—that all dogs are progressively inclined regarding social issues.
