#1. Jon Stewart

When Jon Stewart left the Daily Show as an incredible career as it's host, no-one expected him to appear at Summerslam 2015.
Sure, he had had some weird beef with then-WWE World Heavyweight Champion Seth Rollins, but this had seemingly been dropped on WWE TV following Stewart's departure from the comedy show.

Appearing at Summerslam 2015, in a title-for-title match between Rollins and US Champion John Cena, Stewart was waiting with a chair, as every member of the crowd figured out what was going to happen.
Attacking Cena, it was a swerve so obvious that no-one was shocked, though Stewart at least gave a reason, saying he didn't want Big Match John to tie Ric Flair's 16 World Title reigns.
Just over a year later, Cena would do just that, making Stewart's actions, completely pointless.
