 What is the connection between Attaboy’s name and the perfume Pard teaches Casey to make?
[Transcriber's Note: This etext was produced from Planet Stories Fall 1954. It just ain't big enough for a gent of scope and talent; and the day the Solar System Customs caught me red-handed smuggling Kooleen crystals in from Mars, I knew I was in that corner, and sewed up tight. Sure, the crystals are deadly, but I was smuggling them legitimately, in a manner of speaking, for this doctor to experiment with. But—and this was the 'but' that was likely to deprive the System of my activities—even experimenting with them was illegal even if it needed to be done; also, I had promised not to rat on him before taking the job. Well, Casey Ritter may be a lot of things we won't mention, but he doesn't rat on his clients. "Aw, hell, judge, that's just one of those screwy fairy tales! How could any—" The senior judge rapped ferociously, and I skidded to a halt. That whole Kooleen caper: Had it been just a trap to lead me straight to this? Not when I already had more counts against me than a cur has fleas. Well, a cross between a scorpion and a grasshopper, to be accurate. After all, in the pen a man can eat and breathe, and a guard won't reach in and nip off an arm or leg while he's got his back turned.
 Pard calls the scorpion kid “Attaboy.” Of course, “Attaboy” is a contraction for “that a boy,” but because Attaboy is affected by Pard’s love perfume, he accepts the name as a kind of blessing.
