Ignaz Moscheles’ piano piece “The Way of the World” is invertible — the music reads the same upside down.

Here’s pianist Felix Noel playing it both ways, and here’s a printable score if you’d like to try it yourself.

In May 2009, California consumer Janine Sugawara sued PepsiCo for implying that crunchberries are a fruit. She claimed that she and other consumers had been misled both by the name of the cereal and by the image on the box of Cap’n Crunch “thrusting a spoonful of ‘Crunchberries’ at the prospective buyer.” The package suggests that the product contains real fruit, she said; had she known otherwise, she would not have bought it.

“While the challenged packaging contains the word ‘berries’ it does so only in conjunction with the descriptive term ‘crunch’,” wrote Judge Morrison England Jr., reflecting wearily upon the course his life had taken. “This Court is not aware of, nor has Plaintiff alleged the existence of, any actual fruit referred to as a ‘crunchberry.’ Furthermore, the ‘Crunchberries’ depicted on the [box] are round, crunchy, brightly-colored cereal balls, and the [box] clearly states both that the Product contains ‘sweetened corn & oat cereal’ and that the cereal is ‘enlarged to show texture.’ Thus, a reasonable consumer would not be deceived into believing that the Product in the instant case contained a fruit that does not exist.”

He dismissed the case and denied Sugawara the chance to amend her complaint. “The survival of the instant claim would require this Court to ignore all concepts of personal responsibility and common sense,” he wrote. “The Court has no intention of allowing that to happen.”

To demonstrate “the discovery which I had made of preparing specimens upon scientific principles,” eccentric naturalist Charles Waterton (1782-1865) created “The Nondescript,” a red howler monkey whose face he had manipulated into a semi-human cast.

“I have no wish whatever that the nondescript should pass for any other thing than that which the reader himself should wish it to pass for,” he wrote, rather elliptically. “Not considering myself pledged to tell its story, I leave it to the reader to say what it is, or what it is not.”

The specimen is preserved at the Wakefield Museum in West Yorkshire. Lost is a similar Waterton creation, “The English Reformation Zoologically Demonstrated,” a series of “portraits” of famous Protestants fashioned from preserved lizards and toads.

Such experiments could make Waterton seem unfeeling, but he was fundamentally more sympathetic with the wildlife of South America than the Georgian society to which he’d been born. He made this address to a sloth he surprised on the banks of the Essequibo in Guyana:

“Come, poor fellow. If thou hast got into a hobble to-day, thou shalt not suffer for it: I’ll take no advantage of thee in misfortune; the forest is large enough for both thee and me to rove in: go thy ways up above, and enjoy thyself in these endless wilds; it is more than probable thou wilt never have another interview with man. So fare thee well.”

(“I followed him with my eye till the intervening branches closed in betwixt us; and then I lost sight for ever of the two-toed Sloth. I was going to add, that I never saw a Sloth take to his heels in such earnest: but the expression will not do, for the Sloth has no heels.”)
