Australia fought a “war” against emus (and didn’t win)
In late 1932, Western Australia unleashed soldiers against crop-ravaging emus. For weeks troops peppered the flightless pests from rifles; however, the body count fell dramatically short of estimates and the whole operation became something of a laughingstock across the country. The reason people remember the operation today is precisely its disappointing performance for such a formidable venture.

The U.S. Army tried using camels in the Southwest
The U.S. Army purchased several dozen camels in the mid-1850s to evaluate their capacity compared to horses and mules in hot deserts. The results that came back indicated the animals could handle heat and limited water, but as the Civil War neared, so did any impetus to keep trying new-to-America animals, and auctioneers auctioned off much of the menagerie and scattered it around the West, where it persisted in legend for decades.
The U.S. built a nuclear-powered base under Greenland’s ice as cover for a missile idea
The real thing – a subterranean installation hollowed out in Greenland’s ice, powered at some point by a mobile nuclear reactor and envisioned publicly as a research and engineering display with an associated secret project (Project Ice worm) – considered storing missiles in glacial tunnels. (The ice movement rendered it impossible and the camp was closed).
The CIA spent real money trying to turn a cat into a spy tool
CIA Project on "acoustic Kitty" It may surprise to learn that the CIA indeed tested a cat which would carry an array of listening devices aboard. The practical problem of convincing an outdoorsy cat to comply with its duties was significant. CIA records sometimes recount this operation as a brave endeavor with real world shortcomings.

The earliest well-documented labor strike was recorded in ancient Egypt
In Deir el-Medina – the village where the craftsmen of the royal tombs lived – workers protesting against late food supplies left their tools and held a rally at the temple of Thutmose III. This incident is reported by a scribe on what is usually known as the ‘Strike papyrus’. The workers are supposed to have yelled ‘We are hungry!’ because payment for food did not arrive on day 18 of its due day.
London once had a deadly beer flood
The London Beer Flood: “In this terrible accident, a force crushed nine unfortunate persons to death…” (1814) “The contents of a huge vat of brown porter at the Horse Shoe Brewery burst open and poured into the adjacent street and out onto the street in a destructive wave of beer.”
“This tragedy would see eight lives lost and would leave London…’s stranger history forever. When one of those terrible, great vats exploded at the Horse Shoe Brewery in St George-’s-’ field (42.77):19 on Monday 17th of October last as six o’clock it turned the adjacent street into a furious and irrate tide in’ the size of a house – some people were burnt up entirely by the scald of the porter…(some ten were drowned or crushed… to death)” (William Davies) “In this terrible accident, nine unfortunate persons were crushed to death."
Los Angeles fired over a thousand anti-aircraft shells at nothing in 1942
At the crack of dawn on February 25, 1942-less than two months after Pearl Harbor-the air raid sirens shrieked through Los Angeles as searchlights and anti-aircraft guns flooded the sky. This massive (and apparently unnecessary) alarm in LA eventually blamed the kerfuffle on wartime jitters and misidentification of a weather balloon-no actual enemy invaders in sight.

The oldest known written customer complaint is about bad copper
A clay tablet message to a merchant named Ea-nāṣir is known as the oldest written complaint and reads like a frustrated customer service message you might see today. It’s recognized by Guinness World Records, and the tablet has been held in the collections of the British Museum since the 1950s.
A dead pope was put on trial in 897
The “Cadaver Synod” involved exhuming the body of Pope Formosus and subjecting him to a staged trial with his dead, now very nine months old, body placed upright in front of them in a courtroom. Someone presumably presided over the trial to act in the deceased Pope’s defense, reading off the charges and one of the deacons answered them. The trial found the Pope guilty, which would have been an accomplishment under any circumstance, and then they threw him into the Tiber.
