Afridi tribesmen agreed not to engage in traditional blood feuds on a road through the Khyber Pass after it was seized by the British Raj in 1879. One result, the writer E.F. Benson later reported, was that Afridis would travel through clandestine tunnels to the road to “smile at each other.” Then, “having taken the air,” he wrote, “they rabbit it into their fortresses again.”

Dynamite magnate Alfred Nobel omitted mathematics from the final list of categories his prizes would specifically recognize, claiming the prize for physics would cover it. Rumors circulated—likely helped along by the miffed Gösta Mittag-Leffler, Sweden’s leading mathematician—that this was due to a romantic rivalry between Nobel and Mittag-Leffler; the woman had chosen the mathematician, and punishing the whole field was Nobel’s revenge.

“Mine is a peaceable disposition,” Heinrich Heine writes in his journals, declaring simple wishes: a humble cottage, some fine trees out front. But “if God wants to make my happiness complete,” he adds, “he will grant me the joy of seeing some six or seven of my enemies hanging from those trees. Before their death I shall, moved in my heart, forgive them all the wrong they did me in their lifetime. One must, it is true, forgive one’s enemies—but not before they have been hanged.”

In the Texas border town of Lajitas, generations of goats named Clay Henry have since 1986 served as mayor from a pen outside the general store, where passersby often stop to give them beer.
