"Now Fweep ain't the brightest creature in the Universe, so he can't understand why we're so gosh-fired eager to leave. And as long as he's got Four, he's happy. Why should he make himself unhappy? As a favor to Four, he'd let us leave—if we'd leave Four here with him, which we ain't gonna do. It was a spaceship, but not the kind men had once dreamed about. The you've already got the answer. All you want from it then is decimal points." this computer won't work. It won't even do simple arithmetic! Where's fully equipped, for $15,730. It didn't behave like a spaceship, either. Four? He's the only one who understands this thing." "He's outside, playing in the meadow with Fweep," Reba said, her voice soft. "No, here they come now." knees, his thumb still over the Off-On button on top. "I know it, Fred," he said, frowning. "This world fooled me. It has a diameter 'That looks like heavy metals', and you said, 'Maybe uranium—'" "That's enough, Four," Junior interrupted. "Never mind what I said." remarkably alike, although some vital element seemed to have dwindled until Four looked pale and thin-faced and wizened. "And, Four," Reba said automatically, "don't call your father 'Junior.' It sounds disrespectful." Junior had won her was, to Grampa, the most hopeful thing he had ever noticed about the boy. "But everybody calls Junior 'Junior,'" Four complained. "Besides, Fred is Junior's father and Junior calls him 'Fred.'" "That's different," Reba said. Grampa was still waving his puzzle circuit indignantly. "See!" The "Go back to your games, Grampa," Fred said impatiently. "We've got work to do." Grampa knitted his bushy, white eyebrows and petulantly pushed the last button on his pircuit. The last light went out. "You've got work to do, have you? Whose flivver do you think this is, anyhow?" "It belongs to all of us," Four said shrilly. "You gave us all a sixth share." "That's right, Four," Grampa muttered, "so I did. But whose money bought it?" "You, Grampa," Fred said. "You bet! And who made one hundred million dollars out of it that the before we left, you bought a hundred-year contract with that Life-Begins-At-Ninety longevity company." button. Thirteen slim lights sprang on. "I'll get you this time!" Four stretched and stood up. He looked curiously into the corner by the who makes the other one turn out the last light is the winner." "That's simple," Four said without hesitation. "The winning strategy is to—" "Look!" he said suddenly. "This planet not only has flora—it has fauna." He rushed to the air lock. "Four!" Reba called out warningly. "It's all right, Reba," Four assured her. "The air is within one per quit." "Quit!" Fweep?" Joyce drew her chair farther back toward the wall, revulsion on her face. "Four! Get that nasty thing out of here!" closed and then cocked a white eyebrow at Reba. "Good for you, Reba!" he said admiringly. "For forty years now, I've wanted to do that. Never "It was easy," Grampa said breezily, "once you understood the principle. The player who moved second could always win if he used the right strategy. Dividing the thirteen lights into three sections of four each—" "That's right," Four agreed. "I can make you a new one by cannibalizing the other pircuit, but I'll need a few extra parts." brides, the three jealous husbands, the river and the two-passenger "Yep," Grampa said. "Too easy." Four thought a moment. "There's a modern variation with three missionaries and three cannibals. Same river, same rowboat and only one of the cannibals can row. If the cannibals outnumber the missionaries—" "Sounds good, boy," Grampa said eagerly. "Whip it up for me." followed closely by Junior. They were sweat-stained and weary, scintillation counters dangling heavily from their belts. cramped old flivver—and we don't have many of them to spare!" She glared venomously at Grampa. "We've still got Fweepland," Four said solemnly. "Fweepland?" Reba repeated. "This planet. It's not big, but it's fertile and it's harmless. As it's broken or there's something about the gravity around here that just won't polarize." "It's these '23 models," Grampa put in disgustedly. "They never were any good." The land of the Fweep turned slowly on its axis. The orange sun set and spaceship rested on its improbable stern. The sixteen Earth hours that the rotation had taken had changed nothing inside the ship, either. Grampa snorted. "Broken-shmoken. Nothing to break, Young Fred. Just a few coils of copper wire and they're all right. We checked. We know we won't have to stop with one child. We can have all the babies we "I could think of worse things," Reba said. "I like your spunk, Reb," Grampa muttered. "Speaking of children," Junior said, "where's Four?" "Here." Four came through the airlock and trudged across the room, raspberry shadow, rolled Fweep. "Fweep?" it queried hopefully. "Not now," said Four. "Where've you been?" Reba asked anxiously. "What've you been doing?" "It shifts." "That's impossible," said Junior. "Not for Fweep," Four replied. The land of the Fweep rotated once on its axis, and Grampa lowered the nippled bottle from his lips. He sighed. "I got it figured out, Four," he said, holding out the pircuit proudly. "A missionary takes cannibal takes over the other cannibal and leaves him there and—" "Not now, Grampa," Four said inattentively as he watched Fweep making Four nodded. "And that 'skin' of his—whatever it is he uses for skin—is more efficient in stopping particle emissions than several "Don't call me 'Grammy!' Well, what are we going to do, just sit around and wait for that thing to die?" "We'd have a long wait," Four observed. "Fweep is the only one of his something. He couldn't just have sprung into being as he is now." "Maybe he developed," Four offered. "It seems to me that he's bigger than when we first landed." "He must have been here a long, long time," "He's no more improbable than people," said Four. "Less than some I've known," Grampa conceded. "Some," Four admitted. "Fwiend," it said. "Well, now," Grampa said maliciously, his eye on Joyce, "that's no problem. We can just leave Four here with Fweep." In a voice filled with sanctimonious concern, Joyce said, "That's quite "Never mind, Reba," Four said evenly. "It was just what I was going to suggest myself. It's the one really logical solution." Four is strange enough without encouraging him to think like a martyr. It's out of the question. If that's the only way we can leave this planet, we'll stay here until Four has a beard as white as Grampa's!" "Well!" Joyce said in a stiff, offended tone and sat back in her chair. because he doesn't like gravity that's polarized in a straight line, and he don't want Four to leave him.
