#3. Interrupting Elias' performance
Last year, Elias didn't have any real luck at WrestleMania. He vowed to put on the greatest performance in history, but his first major mistake was teasing that he was The Undertaker, and coming out to a frustrated and angry John Cena, who thought that he finally got his wish after calling out The Undertaker (which he did).
This year, Elias is set to portray the role of the "lead musical act" of WrestleMania, and rest assured, there's going to be some interference or the other. Some of the names thrown in the hat are John Cena, The Rock and even 'Stone Cold' Steve Austin.
While this is likely, wouldn't it be incredible and unexpected if Elias were to suddenly be interrupted by John Oliver of all people? For some reason, we get a gut feel that Oliver and Elias could actually have some good comedic chemistry together, and it would lead to a great segment.
