"Of course I'm all right," I snapped. "But, Freddy," she wailed, "he might have killed you!" I had to laugh. "You mean Arnie?" I snickered. "Why Arnie wouldn't hurt a fly. Besides, it's against the rules for clean-cut American kids to wrestle rough." "I mean Dr. MacCluett," she squalled. "That was a very dangerous operation he performed on you. He might have done an irreparable injury to your poor little brain." In all my life I had never heard such a silly statement. "Panda, I got to tell you something," I sighed. "Even that bear in that carnival couldn't damage my brain. He beat both paws to a pulp on my head, and then said to hell with it. We used to call that bear 'Old Limpy.'"

He--" She reached up suddenly and slipped her arms around my neck. "Oh-h-h, Fred--dy!" she cooed. It was a pleasant sensation. I mean, it was a sort of change from having drinks sloshed over you. For a moment there I began to think science was wonderful. I still hadn't had time to realize my career had just gone down in flames. I still didn't know what an appalling
