When Booker T. Washington and Austrian ambassador Ladislaus Hengelmüller visited the White House on the same day in November 1905, Hengelmüller took Washington’s overcoat by mistake. According to the Washington Post, he noticed the mix-up on finding in the pocket “the left hind foot of a graveyard rabbit, killed in the dark of the moon,” which he “heroically relinquished.”

On Friday, January 13, 1882, thirteen men met in New York City as the Thirteen Club; they walked under a ladder, ate lobster salad sculpted into the shape of a coffin, and sat beneath a banner reading morituri te salutamus (“we who are about to die salute you”). The following year, the club’s newsletter gleefully reported that “not a single member is dead.” 

“The die,” wrote geographer Pausanias circa 150, “is the plaything of youths and maidens, who have nothing of the ugliness of old age.” 

A young nobleman in ancient Athens fell in love with a statue of Agathe Tyche, goddess of good fortune. He hugged and kissed it, then offered the local council a large sum of money to purchase it.

Sailors’ fear of bananas may extend back to seventeenth-century Spanish ships trading in the Caribbean. Crew members would often purchase wooden crates of the fruit, and when their vessels sailed north to pick up the Gulf Stream in the Straits of Florida, hazards of the passage shipwrecked many, leaving behind stray clumps of bananas floating ominously on the water’s surface for later ships to see.

When Apple released its Shuffle feature for iPods, users were deceived by the true randomness of its playback; songs from the same album or artist were often grouped by chance.
