Could be! It was definitely a friend-of-a-friend territory. But often legends of failure are used to warn against real dangers. Little Red Riding Hood is surely fictional, but wolves in the woods definitely weren't.
And at least in Chicago in the 1990s, traders and clerks could definitely be wild. During slow periods on the CME floor somebody would get a transparent trash bag, declare it a $20 bag, and then walk around with it. People would write their names on $20s and throw them in. Once they'd made the rounds, they'd shake the bag and have somebody draw from it. I myself saw thousands of dollars change hands like this. And clerks would regularly bet one another about jumping into the Chicago river from Upper Wacker, which is a fair drop.
Or there was one incident that was witnessed by a couple of our traders, as it happened in their pit at the CBOT. One afternoon among all the colored coats, they see somebody in a polar bear costume walking around the trading floor between the pits. One trader turns to another and says, "I'll pay you $100 if you punch the polar bear." The trader thinks about it, takes the $100, goes over, lays out the polar bear, and then in the chaos goes back to his pit. This turned out to be a bad trade, as the polar bear was there as a fundraiser for the Lincoln Park Zoo, and one of the people on the zoo's board was also on the exchange's board. Oops!
