10 Worst Booking Decisions In SummerSlam History

10. Jon Stewart’s Interference

As far as celebrity appearances go, Jon Stewart’s wasn’t necessarily a terrible one.

Initially, he’d been brought in as the guest host for SummerSlam 2015, which in itself wasn’t a bad decision. He actually did a pretty great job of ushering in the show and hyping up the Brooklyn crowd.

However, later in the evening, someone made the call to afford Stewart rather more responsibility, when he was inserted into the WWE and United States Championship unification bout between Seth Rollins and John Cena. From there, he struck Cena with a chair to gift the victory to Rollins, which was certainly a surprising development, but not a particularly welcome one.

Don’t get me wrong: there’s a time and a place for celebrity appearances. But a title unification match isn’t one of them. To get the fans invested in such a high-stakes contest, only to have the conclusion marred by such shenanigans is a bit of a slap in the face to everyone who paid to see the show.

Again, Stewart’s personal performance may not have been all that bad, but the decision to cast him in such a prominent role is what consigns him to a spot on this list.
