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.
