Pete looks at the thing in his hand, and the Prof and I go over there.
The Professor looks at the thing real carefully and speaks up. "Say, Pete, look at that thing and tell me what it is."
"Why, it's a brand new bar of soap, of course. I don't use it, but one of you might want to. What's all the beef about?"
"Soap?" I say. "Why, you poor fish, something must have happened to your eyes. When you offered me that straight razor, I thought you'd gone off your nut. Now I know it."
The Professor interrupts. He looks excited. "Wait a minute, Eddie. To me that item looks exactly like a full fifth of Old Harvester, 100 proof. Used to be my favorite, before I became an abstainer. To Pete, it looks like soap. To you, it looks like a straight razor while, to Sacks, it resembles a shoe. Does that give you any ideas?"
"Means we're all having hallucinations," I grunts.
"Exactly. Pete, was there anything else in the location where you found this thing?"
"Nothing but some scrap tin."
"Show us."
