Dan Lewis, author of the daily newsletter Now I Know (“Learn Something New Every Day, By Email”) joins us Wednesdays with surprising facts about the world of business.


If you have seen Trading Places, the Eddie Murphy-Dan Aykroyd-Jamie Lee Curtis comedy—or if you are knowledgeable about commodities trading—you probably know what “futures” and “shorting” are.

If not, a “future” is a contract to buy a certain commodity at a date in the future for a price set today. The buyer of the contract hopes the commodity’s price will go up the interim, while the contract’s seller hopes it will go down. “Shorting” (or “short selling”) happens when a seller of a futures contract does not yet own what he or she is selling. Instead, the seller borrows commodity futures from their owner, sells them, and buys them back later. The short seller hopes that the price of the commodity will go down between when he or she borrows it and when he or she repurchases it, thereby making a pretty penny on the difference.

In various points of the movie, Aykroyd and Murphy are trading futures of pork bellies and frozen concentrated orange juice. In fact, futures of almost all commodities can be purchased on public markets. Almost all, because in the United States, onion futures are prohibited from trade—thanks to Dwight Eisenhower, Gerald Ford, and a pair of traders who gamed the system and walked away millionaires.

In 1955, onions made up 20 percent of the commodities traded at the Chicago Mercantile Exchange. Two traders, Sam Seigel and Vincent Kosuga, saw an opportunity. The pair began buying onions and onion futures in huge amounts, cornering the market—by that fall, they ended up with roughly 98 percent of all the onions in Chicago, totaling roughly 30 million pounds of the vegetable.

Soon after, Seigel and Kosuga started to short sell onion futures, effectively betting that the price of onions was about to drop precipitously. This was not a blind gamble, however. The pair began to sell their stockpiled onions, causing a glut of supply, and forcing the price of onions down—way down. In August 1955, a 50-pound bag of onions in Chicago cost about $2.75. By March 1956, the going rate in Chicago for the same amount of onions was a mere 10 cents due to Seigel and Kosuga’s market manipulation. The pair walked away millionaires, and left the onion market in shambles—worthless in Chicago and impossible to find everywhere else. Onion producers were going out of business, and turned to Congress.

Gerald Ford, then a Congressman from Michigan, sponsored a bill outlawing the trade of onion futures—a very specific bill aimed at preventing this very specific type of endeavor. The commodities trading lobby, of course, opposed the bill, threatening litigation if it were signed into law. President Eisenhower called their bluff, signing the Onion Futures Act in the summer of 1958. The Mercantile Exchange sued, and lost. The trading of onion futures is banned in the United States to this day.

The movie industry, at least, is better off for it. Because the Onions Future Act robbed the Mercantile Exchange of a robust market—and therefore, profit center—its leadership needed to expand the offerings in order to maintain a healthy business. The two most notable additions: pork bellies and frozen concentrated orange juice—the two key items dealt in Trading Places.

Bonus fact: In Trading Places, Aykroyd and Murphy’s characters make their killing by engaging in insider trading—they are privy to an advance version of the orange crop report. One would think that, had they been caught, they would go to prison, but this is not the case. As of 2010, insider trading was not, generally speaking, illegal in commodities markets. In fact, that year, the head of the U.S. Commodity Futures Trading Commission testified in front of Congress arguing that this be changed, and in his testimony, he cited to the scheme pulled off in Trading Places.

  • Man’s dog suddenly becomes protective of his wife, Internet clocks the reason right away

    Reddit user Girlfriendhatesmefor’s three-year-old pitbull, Otis, had recently become overprotective of his wife. So he asked the online community if they knew what might be wrong with the dog.

    “A week or two ago, my wife got some sort of stomach bug,” the Reddit user wrote under the subreddit /r/dogs. “She was really nauseous and ill for about a week. Otis is very in tune with her emotions (we once got in a fight and she was upset, I swear he was staring daggers at me lol) and during this time didn’t even want to leave her to go on walks. We thought it was adorable!”

    His wife soon felt better, butthe dog’s behavior didn’t change.

    Girlfriendhatesmefor began to fear that Otis’ behavior may be an early sign of an aggression issue or an indication that the dog was hurt or sick.

    So he threw a question out to fellow Reddit users: “Has anyone else’s dog suddenly developed attachment/aggression issues? Any and all advice appreciated, even if it’s that we’re being paranoid!”

    The most popular response to his thread was by ZZBC.

    Any chance your wife is pregnant?

    The potential news hit Girlfriendhatesmefor like a ton of bricks. A few days later, Girlfriendhatesmefor posted an update and ZZBC was right!

    “The wifey is pregnant!” the father-to-be wrote. “Otis is still being overprotective but it all makes sense now! Thanks for all the advice and kind words! Sorry for the delayed reply, I didn’t check back until just now!”

    Redditors responded with similar experiences.

    Anecdotal I know but I swear my dog knew I was pregnant before I was. He was super clingy (more than normal) and was always resting his head on my belly.

    So why do dogs get overprotective when someone is pregnant?

    Jeff Werber, PhD, president and chief veterinarian of the Century Veterinary Group in Los Angeles, told Health.com that “dogs can also smell the hormonal changes going on in a woman’s body at that time.” He added the dog may “not understand that this new scent of your skin and breath is caused by a developing baby, but they will know that something is different with you—which might cause them to be more curious or attentive.”

    The big lesson here is to listen to your pets and to ask questions when their behavior abruptly changes. They may be trying to tell you something, and the news may be life-changing.

    Why mass shootings spawn conspiracy theories

    Mass shootings and conspiracy theories have a long history.

    While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.

    When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.

    Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
