WWE's pay-per-view history has been built around the four big events of WrestleMania, Royal Rumble, Survivor Series and SummerSlam.
WrestleMania is known for being the grand spectacle and so many "WrestleMania moments."
Survivor Series is filled with unique team combinations as well as controversial moments.
Royal Rumble is great for the quick pace and beginning the road to WrestleMania.
SummerSlam ends every summer and has made a habit of featuring some intriguing swerves to the storylines.
In honor of that, I'm counting down the most shocking moments in the history of SummerSlam.
The marriage of Macho Man Randy Savage and Miss Elizabeth was the original wedding. This attraction in a wrestling ring came long before Triple H was marrying Stephanie McMahon or any other wedding became a popular swerve in the storylines.
The wedding took place in the ring without a problem. Perhaps that should have been a shocking moment as every wedding segment since has been doomed with interruption and disaster. The real shock came at the reception hall where a snake slithered out of a wedding gift marking the arrival of Jake “The Snake” Roberts and The Undertaker to crash the wedding.
At the time, this was unprecedented creative writing in the world of professional wrestling to feature something like this on a pay-per-view.
On the same night WWE moved into new territory with a wedding, they also engaged in a match with a new stipulation.
The Mountie went up against the Big Boss Man and the loser had to spend a night in jail. In traditional wrestling style, the heel loss the match and it was time for the payoff.
It was another original concept by WWE who gave us the payoff but did it periodically as the night went on. We first saw The Mountie leave Madison Square Garden with the police. They continued to show clips throughout the night as he got photographed and booked into a New York City jail.
I don't know what people expected to see out of this match when it was advertised, but I do think the whole segment goes down as a shocking moment in SummerSlam history.
Whenever you have a champion, they eventually will lose. So, it shouldn't have been any surprise the Honky Tonk Man eventually would lose the Intercontinental title after holding it for 64 weeks. What was a surprise was how quickly he would be defeated.
He put out an open challenge and the Ultimate Warrior answered it. It took 31 seconds for the rising star to beat Honky Tonk Man and crowned new champion.
A shocking moment nobody expected to see.
It was a controversial topic in the summer of 2010 when Daniel Bryan was released after his debut night on the main roster as a member of Nexus.
Bryan was released courtesy of his actions of choking ring announcer Justin Roberts on television and it being deemed inappropriate based on company standards. Two months later, Bryan would make his surprise return as part of John Cena's team to battle Nexus at SummerSlam.
A shocking moment in SummerSlam history that is all the more interesting now that three years later Bryan and Cena are in the main event against each other.
Kevin Nash coming out of the crowd in the main event match was the second most shocking moment in SummerSlam history.
It was totally out of left-field with his appearance and giving a powerbomb to CM Punk. The only other WWE appearance for Nash in the previous eight years was as Diesel for a one-night at the Royal Rumble 2011. Nash being worked back into weekly storylines and his target being Punk came as a huge shock.
Unfortunately, no payoff ever took place between the two in Nash's return run with the company.
Paul Bearer turning his back on The Undertaker is the biggest and most shocking moment in SummerSlam history.
The pairing of the two was so popular. There was no reason to think the pair would ever split up. There was no foreshadowing or teasing of a potential breakup. At the time there was nobody else on the WWE roster you could picture seeing Bearer manage.
In the first ever boiler room brawl, The Undertaker and Mankind fought their way from basement to ring in a sold-out arena in Cleveland. The image of Bearer smashing the urn over The Undertaker's heads tops the list of most shocking moments at SummerSlam with the emotional and entertainment weight it held.
