the matter?" inquired Darter's master. "I thought you liked dog fights, Butch." "I do like dog fights," Butch said somberly, without looking around. "I don't like uninj fights. They're just a pretend, like everything else. Nobody gets hurt. And look here, Joggy—and you, too, Hal—when you talk to me, don't just say Butch. It's the Butcher, see?" "That's not exactly a functional name," Hal observed with the judiciousness of budding maturity, while Joggy said agreeably: "All right, Butcher, I suppose you'd like to have lived way back when people were hurting each other all the time so the blood came out?" "I certainly would," the Butcher replied. As Joggy and Hal turned back skeptically to watch the fight, he took out the metal tube, screwed up his face in a dreadful frown and jabbed himself in the hand. He squeaked with pain and whisked the tube out of sight. "A kid can't do anything any more," he announced dramatically. "Can't break anything except the breakables they give him to break on purpose. Can't get dirty except in the dirt-pen—and they graduate him from that when he's two. Can't even be bitten by an uninj—it's contraprogrammed." "Where'd you ever get so fixated on dirt?" Hal asked in a gentle voice acquired from a robot adolescer. "I've been reading a book about a kid called Huckleberry Finn," the Butcher replied airily. "A swell book. That guy got dirtier than anything." His eyes became dreamy. "He even ate out of a garbage pail." "What's a garbage pail?" "I don't know, but it sounds great." The battling uninjes careened into them. Brute had Darter by the ear and was whirling him around hilariously. "Aw, quit it, Brute," the Butcher said in annoyance. Brute obediently loosed his hold and returned to his master, paying no attention to his adversary's efforts to renew the fight. The Butcher looked Brute squarely in the eyes. "You're making too much of a rumpus," he said. "I want to think." He kicked Brute in the face. The dog squirmed joyously at his feet. "Look," Joggy said, "you wouldn't hurt an uninj, for instance, would you?"
