Legend regarding the horseshoe as a lucky symbol holds that in the tenth century, while St. Dunstan was working in England as a farrier, the devil entered the forge and demanded his hooves be reshod. During the process, the future saint caused as much pain as he could, and the devil begged him to stop. Dunstan agreed—on the condition that Satan never enter a house where a horseshoe is on display.

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.”

Suetonius reported that Caligula often cheated when playing dice. The emperor once interrupted a game to go into the courtyard, where he spotted a group of rich knights passing. He had them arrested, stole their goods, then “resumed the game in high spirits, boasting that his luck had never been better.”

In November 1934 a team of American baseball stars, including Babe Ruth, toured Japan. When they arrived for a game in the town of Narashino, each man was presented with a horseshoe-shaped flower wreath. Ruth detested the gift; he later told a Japanese baseball magazine that he considered such wreaths bad luck and had never hit a home run after receiving one.

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.

A twelfth-century-bc Chinese king consulted an oracle and was told his lucky charm would not be a tiger, dragon, bear, or leopard but rather a wise counselor. He soon came upon a sagacious old man fishing in the river and conscripted him into service. It is said the man’s virtue was such that he fished not with a hook but with a straight piece of iron; acknowledging his integrity, fish impaled themselves voluntarily.
