<passage>:
Getting specimens for the interstellar zoo was no problem—they battled for the honor—but keep a display from making a monkey of me! It was our first day of recruiting on the planet, and the alien life-forms had lined up for hundreds of feet back from my rented office. As I came down the block from the hotel, I could hear and see and smell them with ease. My three staff men, Auchinleck, Stebbins and Ludlow, walked shieldwise in front of me. I peered between them to size the crop up. The aliens came in every shape and form, in all colors and textures—and all of them eager for a Corrigan contract. The Galaxy is full of bizarre beings, but there's barely a species anywhere that can resist the old exhibitionist urge. lot better than forking over a hundred grand, isn't it?" giving this slyster a contract might be a risky proposition. Gorb shrugged. "What have I to lose?" arrival. Stuff like this: Want to visit Earth—see the Galaxy's most glittering and exclusive world? Want to draw good pay, work short hours, experience the thrills of show business on romantic Terra? If you are a non-terrestrial, other species of the universe. The office buzzer sounded. Auchinleck said unctuously, "The first certain information about—" "I am a being of Regulus II," came the grave, booming reply, even before I had picked up the blank. "I need no special care and I am not a fugitive from the law of any world." remaining in place. On his world, that gesture is the equivalent of an apologetic smile. "My Regulan name no longer matters. I am now and shall evermore be Lawrence R. Fitzgerald. I am a Terraphile, you see." transportation." The spherical creature clapped his hands in joy, three hands clapping on one side, two on the other. "Wonderful! I will see Earth at last! I accept the terms!" I grinned, pleased with myself. We needed a green Regulan in our show the last one had quit four years ago. But just because we needed him didn't mean we had to be extravagant in hiring him. A Terraphile alien who goes to the extent of rechristening himself with a Terran monicker would work for nothing, or even pay us, just so long as we let him get four feet high and five hundred pounds heavy. We already had a couple of his species in the show, but they made good crowd-pleasers, being the successful proprietor of Corrigan's Institute, after some years as an impoverished carnival man in the Betelgeuse system. Back in 2903, the World Congress declared Terra off-bounds for non-terrestrial beings, as an offshoot of the Terra for Terrans movement. Before then, anyone could visit Earth. After the gate clanged down, a non-terrestrial could only get onto Sol III as a specimen in a scientific collection—in short, as an exhibit in a zoo. That's what the Corrigan Institute of Morphological Science really is, of course. A zoo. But we don't go out and hunt for our specimens we advertise and they come flocking to us. Every alien wants to see Earth once in his lifetime, and there's only one way he can do it. We don't keep too big an inventory. At last count, we had 690 specimens before this trip, representing 298 different intelligent life-forms. My goal is at least one member of at least 500 different races. When I reach that, I'll sit back and let the competition catch up—if it can. After an hour of steady work that morning, we had signed eleven new specimens. At the same time, we had turned away a dozen ursinoids, fifty of the reptilian natives of Ghryne, seven Sirian spiders, and no less than nineteen chlorine-breathing Procyonites wearing gas masks. It was also my sad duty to nix a Vegan who was negotiating through a Ghrynian agent. A Vegan would be a top-flight attraction, being some how we could take one on. They're gentle and likable beings, but their upkeep runs into literally tons of fresh meat a day, and not just any close look at the life-form when it came in, and after that I took another one. I wondered what kind of stunt was being pulled. So far as I could tell, the being was quite plainly nothing but an Earthman. about him. He said, in level Terran accents, "I'm looking for a job with your outfit, Corrigan." "There's been a mistake. We're interested in non-terrestrials only." "I'm a non-terrestrial. My name is Ildwar Gorb, of the planet Wazzenazz XIII." I don't mind conning the public from time to time, but I draw the line Earthborn as I am." "I've never been within a dozen parsecs of Earth," he said smoothly. "I happen to be a representative of the only Earthlike race that exists from Earth, stranded here and out of cash. You want a free trip back to another chance." He slammed the door and I let my grim expression relax into a smile. This was the best con switch yet—an Earthman posing as an alien to get a job! But I wasn't buying it, even if I could appreciate his cleverness intellectually. There's no such place as Wazzenazz XIII and there's only one human race in the Galaxy—on Earth. I was going to need some real good reason before I gave a down-and-out grifter a free ticket home. I said, "I'd better tell you right at the outset that we're already carrying our full complement of Stortulians. We have both a male and a female now and—" "She lied! She left my burrow because she longed to see the splendors of Earth. And I am alone, bound by our sacred customs never to remarry, languishing in sadness and pining for her return. You must Earth!" "But—" My face was expressionless. "You don't really intend to join our organization at all—you just want free passage to Earth?" "Yes, yes!" wailed the Stortulian. "Find some other member of my race, happy—not to mention footing the transportation. I said, "I don't see how we can manage it. The laws are very strict on the subject of bringing alien life to Earth. It has to be for scientific purposes only. And if I know in advance that your purpose in coming isn't scientific, I can't in all conscience About fifty more applicants were processed without a hitch. Then life started to get complicated again. Nine of the fifty were okay. The rest were unacceptable for one reason or another, and they took the bad news quietly enough. The haul for the day so far was close to two dozen new life-forms under contract. I had just about begun to forget about the incidents of the Kallerian's outraged pride and the Stortulian's flighty wife when the door opened and the Earthman who called himself Ildwar Gorb of Wazzenazz XIII stepped in. outside is . He doesn't know how to handle alien beings. How many times today has a life-form come in here unexpectedly?" I scowled at him. "Too damn many." "You see? He's incompetent. Suppose you fire him, take me on instead. I've been living in the outworlds half my life me. But get this: I just want to finish off my recruiting, pack up and go home to Earth. I don't want you hanging around here bothering me. I'm not looking to hire new staff members, and if you switch back to claiming you're an unknown life-form from Wazzenazz XIII, the answer is arrival. The small figure of the Stortulian trudged through the open doorway come, to figure out some more effective way of screening myself against crackpots. In heart-rending tones, the Stortulian declared, "Life is no longer
