Life on the trading floor is different these days.

Not only are there fewer people on the different exchange floors in the U.S., but traders now have to worry about lower trading volumes and the euro going down the drain, just to name a few things.

And life as a trader is also different in the sense that the tradition of trading floor humor has subsided in recent years.  

According to a veteran trader, who spoke only on the condition of anonymity, traders aren't pulling pranks and jokes on each other like they used to.  

"Fortunately, or unfortunately, you don't see those pranks anymore," the trader told Business Insider.

These pranks and jokes included anything from powdering shoes or taping spurs to shoes to sticking cutout shapes on another person's back. 

The reason for the pranks in the past, the trader explained, is that they helped everyone on the floor "blow off steam."  

"You can't be running at 100 percent all the time.  You need to break the tension and that's why on the floor, every floor, they'd have some sort of prank or joke," the trader told Business Insider. 

Another reason there are fewer pranks is that the New York Stock Exchange emerged as a publicly traded company, meaning there are more sensitive eyes these days. The CME Group, which owns the Chicago Board of Trade and the New York Mercantile Exchange, is also publicly traded.

"We always had respect for what we did as a living -- it was just joking around.  Once we went public the world was watching," the trader said, adding, "Now it's strictly business once everyone went public. Everyone down here is holding the utmost respect."  

We reached out to veteran traders both in New York and Chicago and compiled the most classic floor pranks they used to pull back in the day.

Traders in the pits in Chicago had to watch out for 'gum bombs.'

The Prank: What's a "gum bomb"?  

A veteran trader from Chicago told us that this is when you stick a wad of chewed up gum on the back of a trading ticket and flick it on the floor so someone will step on it and get it stuck to the bottom of their shoe. 

"I got gum bombed all the time," the veteran CBOT trader, who spoke on the condition of anonymity, told Business Insider. "I'm really a clumsy guy."

Meanwhile, at the NYMEX they would pull out the rotten eggs.

The Prank:  A trader once left his jacket out and another trader slipped a rotten egg into one of the pockets.

The trader was walking around the next day wearing the jacket trying to figure out what that awful smell was and eventually he realized someone was messing with him.    

Another trader told us that sometimes traders would randomly toss an egg into the commodities pits.  

Of course, we're told that's not the case anymore.

NYMEX traders would also tell the intern to find the keys to the clearinghouse.

The Prank: A trader told us a prank they used to pull on the floor was directing the intern to go find the keys to the clearinghouse. 

The intern would then bounce all over the place searching for the keys asking different people and being sent in different directions. 

The thing is, there is no clearinghouse.

Sometimes NYSE floor traders would baby powder bomb someone's newly shined shoes so the person would do a silly dance.

The Prank: Back when the floor of the NYSE was jam-packed, a floor trader could come up behind someone with a bottle of baby powder while that person was engaged in a serious conversation.  

The person with the baby powder would then put their arm around the trader and puff the powder on the guy's shoes.    

Of course, everyone had their shoes shined so when they looked down they'd notice the powder and start stamping their feet in a sort of dance and a cloud of white powder would rise up.

Then the people around them would start chanting "Heya, Heya, Heya!."  

"It was such a stupid gag -- so corny!," a trader said.

NYSE traders would also attach toy cars on long strings to other traders' mesh jackets.

The Prank: A lot of the floor traders wear mesh jackets and those tiny holes are really convenient for attaching things.    

A popular trick was to take a long piece of string attached to a paperclip.  At the end of the the 15-foot long piece a string was a toy car. 

A trader would sneak up behind another person and attach it to their jacket.  The result would be that the trader was wheeling around a little toy car without even realizing it.

Sometimes they would bet each other to stuff their faces with Big Macs.

The Prank:  OK, so eating contests aren't really a prank, but more of a humorous tradition.  

They're pretty much ubiquitous with trading floors, especially at banks these days. 

During the summer doldrums (i.e. those warm summer days when people would rather hang outside the office and so trading volume drops) there would be eating contests on the floor, a trader told us. 

Back in the day, there was one where someone had to eat 10 Big Macs for $10K. (We're assuming there was a time limit on this one). 

"I've never seen anyone do it," a trader told us.  "I have seen a Big Mac come out of someone's nose on No. 7."

One time a group of traders made another trader think he had won the lottery.

The Prank:  This is not a floor prank tradition, but a trader told us this one guy used to play the lottery religiously so they decided to mess with him a bit.

The lottery playing trader kept a stack of tickets and a paper.

One day some traders took his newspaper and they played Saturday's numbers and put it in his stack so he appeared to have the winning lottery numbers.  

"The guy thought he won the lottery until he looked at the date on the ticket!"

Naturally, he was disappointed.

CBOT traders used to pull off the 'classic' shark fin in the pit prank.

The Prank:  Veteran traders from the CBOT told Business Insider that they would take a trading card, or two, and fold it into the shape of a fin.  Then they had to carefully slide it under someone's collar so it looked like they had a fin on their back.  Then everyone would scream "SHARK!"

"This was a tough one," a trader told us explaining you had to have very dexterous hands.  "They would be pissed if they caught you." 

"It's a classic," another trader said.

If a fin isn't bad enough, some traders got tails pinned to them.

The Prank:  If traders didn't watch out, they might be walking around with a tail of ticker tape.  

Traders would take the ticker tape and attach it to the bottom of their coats.

Sometimes it was funny to shoulder tap your boss just to tick him off a bit.

The Prank:  "My favorite was the shoulder tap," a trader told us.  "You would stand on the left and tap on the right shoulder and then look away.  The person would say 'who's tapping me?'"  

The trader said he had a boss who never appreciated it and would swear at him.

A lot of the trading floor pranks involve being crafty with scissors and paper.

The Prank(s):  We're told it was popular to cut things out of paper and stick it on someone's back.  

For example, a trader might cut out a knife out of paper and stick it on another person's back.

Speaking of paper cutouts, who could ever forget the infamous 'Who put this d*** on my back?' prank pulled off by a CBOT trader in 2007. Enjoy!
