"Time has not softened my opinions on this matter. It is my belief that, as a rule, creatures of Happy's ilk — I am thinking here of canines and men both — more often run free than live caged, and it is in fact a world of mud and feces they desire,  a world with no Art in it, or anyone like him, a place where there is no talk of books or God or the worlds beyond this world, a place where the only communication is the hysterical barking of starving and hate-filled dogs."

- Joe Hill, "Pop Art," collected in American Fantastic Tales, volume 2
