#2 John Cena takes a shot at The Undertaker
In today's era of social media where kayfabe is almost dead, very few wrestlers still maintain character even off the screen. Nobody does this better than The Undertaker. The veteran is very rarely seen making public appearances out of character and does not even have a social media account!
This is why the fans were stunned when Cena took a shot at the Deadman for posting workout videos on his wife Michelle McCool's Instagram account. This was probably the first time a wrestler has referred to The Undertaker's off-screen persona on live TV, and because of this, the feud immediately escalated to the next level.
