The typical rugby player is tougher than week-old steak, so a fan getting angry and attacking them is almost certainly asking for a trip to the hospital. Perhaps that’s why this crazed fan went after the poor referee instead.

During an August 10, 2002, match between the South Africa Springboks and the New Zealand All Blacks, Springboks supporter Piet Van Zyl decided he didn’t like how referee Dave McHugh was doing his job. He disapproved so much, in fact, that he ran onto the field and grabbed McHugh, throwing him to the ground and dislocating his shoulder. He might’ve done more, except security and rugby players pulled him off McHugh and away from the field. The commentators immediately abandoned impartiality, repeatedly calling Zyl “pathetic,” observed how “he couldn’t even get the tackle right,” and opined that “for our country this is not a good sign at all.” Zyl got his nose bloodied by a rugby player, and later earned himself a lifetime ban from any South African rugby field, along with charges of assault.

An eyewitness account via Rugby Dump says the scofflaw made it perfectly clear he wasn’t sorry. He claimed McHugh had it coming, due to his supposedly poor officiating. Also, Zyl apparently had it out for McHugh since 1995, when the ref ejected a Springboks player from a game. Maybe Zyl should find himself another sport, along with tons of therapy.

Inter Milan supporters went way too far when supporting their team in April 2005, when actual weaponized assault reared its ugly head, endangering a player’s life and causing an important soccer match to end early.

During the quarterfinals of that year’s Champions League tournament, Inter Milan took on AC Milan. AC was up 1-0 after 73 minutes, when Inter finally scored on its rival. Unfortunately, the referee waved off the goal, instead calling a foul against Inter. That, according to the Sydney Morning Herald, made the hardcore Inter fans super mad, and they started throwing flares onto the field. One hit the head of AC’s goalkeeper, Dida, and the referee quickly stopped the match and got all the players off the field, waited a bit, then tried to restart the match. But soon after the match restarted (with Dida on the sideline), Inter fans started throwing more flares. Finally the ref had enough and called the game early.

Thanks to these “fans,” Inter was punished hard. As the BBC reported, not only were they hit with a loss, they were fined £132,000 (about $184,000) and were banned from playing in front of fans for four European games, which means even less money. Thankfully, it also means no flares.

This story’s more silly than anything else, but it’s still an example of how even goofy fan gestures can mess things up for the team that’s supposedly being helped by the move.

In September 2009, the Spartak Moscow soccer team was set to take a penalty kick against FC Saturn. As the Spartak player readied himself for the kick, a fan ran onto the field and interfered. Luckily, he didn’t try to fight anybody, but he did kick the ball. Impressively, he actually got it into the net, though that was more because the goalkeeper was too busy staring at him in utter confusion to even attempt a block.

Perhaps because he was on home turf and because he wasn’t actually hurting anybody, the fan got to run around the field for a while, as did a buddy of his. They celebrated like they had just won the World Cup, and the crowd roared their approval. Once they exited the field, the Telegram reported Spartak kicked for real and also succeeded. Unfortunately, Spartak lost the game — whether that was due to one of their supporters messing up their concentration or if it was bound to happen anyway, no one knows for sure. Either way, if you’re a fan and want to kick a soccer ball during a professional game, practice until you’re good enough to get signed, like a real player.

On May 16, 2000, the Los Angeles Dodgers faced the Chicago Cubs. That day, according to CBS Chicago, an overzealous Cubs fan named Josh Pulliam decided to mess with the visiting team.

Pulliam made his way into the Dodgers’ bullpen (which is right on the first base line), grabbed catcher Chad Kreuter’s hat, punched him in the head, and ran into the crowd. He shouldn’t have done any of those things, but Kreuter and his fellow bullpen buddies didn’t respond very well either. Rather than let security deal with Pulliam, Kreuter and friends gave chase and began to fight the fan. This escalated into fighting other fans, as the Dodgers dugout and bullpen emptied in response.

After a 10-minute delay, play resumed. Ultimately, as the New York Times reported, just about everyone involved got punished. Several fans were ejected and charged with disorderly conduct, while an incredible 16 Dodger players (plus three coaches) were fined and suspended. Luckily for the team, the players didn’t have to serve their suspensions at the same time, since L.A. actually needed players to put on the field. Years later, according to the Chicago Tribune, a fan whom Kreuter choked in anger sued the Cubs for charging him and won $475,000. All this because one guy couldn’t leave somebody else’s hat alone.
