The controversy surrounding Philadelphia Eagles fan Ryan Caldwell berating a female Packers fan during a game is just the latest incident of unruly fan behavior in the sports world.
Other unhinged fans also got into physical altercations with players, with one incident even resulting in a player being stabbed.
Fox News Digital takes a look at five of the most infamous fan moments in sports history.
During Game 6 of the 2003 National League Division Series against the then-Florida Marlins, Chicago Cubs fan Steve Bartman reached out and grabbed a potentially catchable ball.
At the time, Chicago led 3-0 and was expected to seal a trip to the World Series with a win. Bartman interfered with a foul ball hit by Marlins slugger Luis Castillo while Cubs outfielder Moises Alou was trying to catch the out. But Bartman stole the ball out of the air before Alou could catch it, costing his team a valuable out opportunity. This will be the second inning of the game.
But instead, Castillo's next pitch went wild and the Cubs defense collapsed, resulting in eight runs. The Cubs then lost the series in Game 7, extending the team's nearly century-long World Series title drought. Bartman's incident became an infamous moment considered one of the greatest curses in sports history.
The team never won a championship from 1909 to 2016, which is linked to the "Curse of the Billy Goat" superstition, which stems from an incident in 1945 when a fan was arrested for carrying a goat with him. Refuse to watch the game.
Bartman's actions were not motivated by malicious intent, but the aftermath, fallout, and image of him in that game is what made it so infamous.
Details of Bartman's personal life were made public, and he actively avoided public attention for years after the incident. He turned down multiple interviews and opportunities to appear in documentaries.

Caldwell isn't the first Eagles fan to exhibit questionable behavior during a game.
In 1997, during a Monday night game against the San Francisco 49ers, a mischievous Eagles fan opened fire with a flare gun into stands filled with other fans, endangering multiple lives.
Several fights broke out around the stadium after the flares were fired, with much of the violence being directed at Eagles fans against 49ers fans.
"There were numerous fights and acts of intimidation, many directed at fans wearing 49ers jerseys," the Philadelphia Inquirer wrote at the time.
After the game, Eagles owner Jeffrey Lurie was forced to condemn his own fans.
"While we feel we have made significant progress in recent years regarding fan behavior at Veterans Stadium, what we witnessed last Monday was certainly a step backwards," Lurie told reporters at the time.
Veterans Stadium, the team's former home, has an on-site judicial court and jail for dealing with illegal fans.
A 2004 game between the Detroit Pistons and Indiana Pacers turned into one of the ugliest moments in NBA history when a player began attacking fans.
The fight started with seconds remaining, but things got so bad that the fight never ended.
Everything starts with a foul. After the players started fighting on the pitch, it didn't take long for the conflict to escalate into the stands, where spectators began throwing drinks and trash at the players. Pacers forward Ron Artest was at the center of the chaos, and the image of him shaking his fist at Detroit fans became a disturbing staple of NBA lore.
When the Pacers return to the locker room, they must cover their heads to prevent liquids and trash from being spilled on them.
As a result of this incident, multiple fans were banned from attending Pistons games for life. According to sources, a total of nine players have been suspended without pay, totaling 146 games. The five players were charged with assault.

In 1974, the Cleveland Indians (now the Guardians) hosted an event now known as "10 Cent Beer Night." The team sold beer for $0.10 a bottle during a December 2019 game against the Texas Rangers.
The promotion drew 25,134 fans to Cleveland Stadium, many of whom rioted in the ninth inning.
Cleveland's rally to tie the game in the final inning sparked chaos after drunken fans set off firecrackers and rampaged naked around the field eight games earlier. After the game was tied, a fan ran onto the pitch and tried to steal Rangers player Jeff Burroughs' hat from his head.
In response, Texas head coach Billy Martin and his players ran onto the field to protect Burroughs, but that only angered more drunken Cleveland fans to get involved. A mob of spectators armed with knives, chains and clubs made from torn-up seat fragments charged at Texas players.
Some fans even threw steel folding chairs at players, and Cleveland reliever Tom Hilgendorff was hit in the head with one.

Cleveland players swung their bats to help save Texans players from drunken fans.
Teams fled the field in droves through the dugouts and locked themselves inside the clubhouse. But the riot on the court continued for at least another 20 minutes as police and security tried to subdue the rioters. Only nine fans were ultimately arrested.
Chief referee Nestor Chirac ultimately declared Cleveland to forfeit the game and Texas won.
