There are a lot of ways to botch a move in professional wrestling. Some end hilariously and others end with gruesome injuries. Throughout the years there have been some absolutely ridiculous moments that everyone involved wishes they could forget. Here are 10 of the worst botched moves in the history of pro wrestling. Special thanks to the True Life GroupMe for finding some of these gems.

There are a lot of things you don’t learn about being a wrestler until after you get into the ring. However, knowing how to pin your opponent isn’t one of those things. Cameron was taking on Naomi on Monday Night Raw and apparently forgot that you can only pin someone while they’re on their back. “Count it ref!”

The problem with having a finisher that requires you to put your opponent on your shoulders and toss him into the air is that you have to put your opponent on your shoulders and toss him into the air. CM Punk learned that the hard way in a 2010 match against Kane on Smackdown. He attempted his signature GTS, but to say the move didn’t go as planned is a serious understatement.

At WrestleMania 19, Brock Lesnar and Kurt Angle were having an absolutely incredible match filled with non-stop highlights. Then Brock Lesnar decided to attempt a Shooting Star Press off the top rope. If you’re not familiar with a Shooting Star Press, it’s basically a standing backflip onto your opponent. Lesnar ended up landing awkwardly and suffering from a concussion. Somehow he still finished and won the match.

Is it any surprise that, at one point, Donald Trump was involved in a WWE storyline? Vince McMahon and Donald Trump embarked in The Battle of the Billionaires at WrestleMania 23 with special guest referee Stone Cold Steve Austin. Trump was supposed to get hit with a Stone Cold Stunner, but ended up just kind of leaning over and stumbling over his own feet. It certainly wasn’t a high point for anyone involved.

You could easily fill an entire list of nothing but Undertaker injuries. It’s understandable consider the length of his stellar career, but one of the scariest moments was at WrestleMania 25 in his match against Shawn Michaels. He was doing a suicide dive out of the ring and was supposed to be caught by the cameraman. It didn’t go as planned and The Undertaker ended up landing on his head. It’s remarkable he’s been able to be a dominant force in pro wrestling for more than 30 years.

Airing a pre-recorded program allows you to make edits and adjustments, but thanks to the internet and the fact that everyone has a camera on their phone, we get to see when things don’t go as planned. In 2009 Triple H took on John Morrison in a tables match on Smackdown. The way to win is by putting your opponent through a table. John Morrison ended up flying over his table instead of going through it, so they simply set it all back up and did it over again. For the recording, it was fine, but for the live crowd it was definitely less than exciting.

Ladder matches bring a whole new element to high impact matches, but at WWE Armageddon 2006, things went very wrong for Joey Mercury. After Matt Hardy jumped from the top rope, Mercury was in the wrong place at the wrong time and got the full force of the ladder into his face. He immediately left the match covered in blood with a broken nose and a broken orbital bone.

What was supposed to just be a squash match between Triple H and an unknown jobber, almost turned tragic. Marty Garner was about to take a pedigree from Triple H, but he flipped back into it and ended up landing directly onto his head. He suffered neck injuries, but thankfully was able to walk away from the incident.

Owen Hart and Steve Austin had a big match at SummerSlam 97, but things came to an abrupt halt when Hart executed a pile driver on Austin and ended up dropping all of Austin’s weight onto his head and breaking his neck. Somehow Austin was still able to roll up Hart for the pin and win the match.

In what may be the most infamous moment in professional wrestling, The Shockmaster had a debut that no one will ever forget. He was being introduced as the surprise partner for Sting and The British Bulldog, but the wall he was supposed to crash through didn’t open as planned, so he ended up falling flat on his face. To be fair to The Shockmaster, even if things went as planned, it was just going to be a husky guy in a cutoff shirt and a glittery Storm Troopers helmet.
