11. Mankind vs. The Undertaker: SummerSlam 1996
The infamous Boiler Room Brawl. This match opened so many doors for future WWE matches, as it was one of the first times a match actually started somewhere other than the ring.
The Undertaker and Mankind, as they would do many more times following this match, beat each other to a pulp in this match. However, it took Paul Bearer turning on The Undertaker and shockingly aligning himself with Mankind.
To this day, no superstar ever had the number of The Undertaker the way Mankind did during this time period in WWE history.
