#2 Brock Lesnar demanded to go on first at WrestleMania 35
WWE WrestleMania 35 was a historic and thrilling night for many fans. Kofi Kingston finally won the WWE Championship after 11 long years and Becky Lynch, Ronda Rousey and Charlotte Flair made history by becoming the first female wrestlers to headline The Show of Shows. Brock Lesnar, however, was not satisfied that his Universal Championship match with Seth Rollins wasn't the main event.
According to reports, The Beast verbally abused Vince McMahon backstage after getting angry that his match wasn't going on last. He then demanded it go on first instead, changing the plans at short notice. If any other Superstar made such a huge demand like that to Vince McMahon, they would've probably ended up getting fired at the spot, but since Brock Lesnar had the Chairman's number, his wish was granted once again.
Lesnar reportedly flew home almost immediately following the match, while the show was still taking place. The Beast had another incident with Vince McMahon at the previous WrestleMania event after he threw his Universal Championship belt at the latter in the gorilla position after defeating Roman Reigns to retain the title.
