In Animal Farm, what was the pigs' new slogan in chapter 10?

Another new slogan in chapter 10 is "Four legs good, two legs better!"  The pigs have begun to walk on two legs in this chapter, much to the surprise of the other animals.  Just before this happened, Squealer took the sheep out to a distant pasture to teach them a new song (the slogan about 2 legs).  When the pigs make their two-legged debut, the other animals don't know how to react.  "Amazed, terrified, huddling together, the animals watched the long line of pigs march slowly round the yard.  It was as though the world had turned upside-down" (p. 117).  Soon after this display, Clover and Benjamin discover that the seven commandments have been reduced to one:  "All animals are equal, but some animals are more equal than others" (p. 118).
