#2 Randy Orton mocked Eddie Guerrero's passing
In WWE and outside the ring, Eddie Guerrero and Rey Mysterio were considered family. The best friends built an extremely close bond over the years.
In 2006, a few months after Eddie Guerrero's tragic passing, Randy Orton and Rey Mysterio were due to face each other at the No Way Out pay-per-view. The winner would become the No.1 contender for the World Heavyweight Title at WrestleMania 22.
Randy Orton, being the sinister heel, decided to name-drop Guerrero during a promo with Rey Mysterio. Orton declared Eddie wasn't in heaven, but he was in hell. It was another cheap way for WWE to gain heat for a superstar but was immediately met with backlash from fans worldwide.
#1 DDP stalked The Undertaker's wife in WWE
During the tail-end of the Attitude Era, WWE devised a storyline that Diamond Dallas Page would stalk The Undertaker's then-wife, Sara. We initially didn't know who the stalker was, but it was eventually revealed on the June 18, 2001, episode of Monday Night RAW.
Stone Cold Steve Austin refused the contentious WWE storyline pitch when offered to him. The Undertaker was being mocked each week after seeing his wife Sara being stalked.
The feud ended when Sara pinned DDP on an episode of RAW just a few weeks after the reveal.
