Caves in Slovenia run deeper than you think. I walked into one with a torch and a ham. After a week, I came out in Greece, and I asked a shepherd the time. He told me the year instead. I had missed two wars and a very nice wedding.

Comets are simply horses with good lungs. I roped one over Sweden and rode it bareback past Saturn. The tail singed my britches. At the far turn I jumped off and landed in a haystack near Malmo, just in time for a rather dull wedding.

Cats are not to be trusted with maps. Mine led me from Lyon to Cairo in search of a fish. We crossed two deserts and a very long sofa. At the end of it, she sat on my map, yawned, and demanded that I carry her home.

Rivers run downhill because they have never met me. I once talked the Danube into going the other way for an afternoon. Boats sailed up to Ulm without any effort. Then a fish complained to the mayor, and I let the old river go back to its usual job.

Trout leap into my hat when I whistle. In Scotland I proved it before an earl and a crowd of doubting anglers. Nine fish came at the first note. At the second, a small pike, two boots, and a rowboat followed. The earl gave up fishing and took up prayer.

Earthquakes are just the ground getting an itch. In the hills of Persia I took a long rake and scratched the worst of it. The ground let out a low sigh. The shaking stopped at once, and the shah gave me a fine rug that I had to hold down.

Her Imperial Highness asked me to fetch a star for her hair. I borrowed a long ladder from a Kiev fire brigade. The star was hot, so I carried it.
