2. Walking Out On Vince
In February, then-WWE Champion Brock Lesnar walked out during the live airing of Monday Night Raw. Reported reasons for his departure include his frustration at not being able to thrash out details on a new contract with Vince McMahon - it seems Lesnar is a relatively straight-forward man when it comes to these things, and doesn't like waiting it out at the negotiating table. This must have been a tough one for Vince to swallow. Lesnar had been scheduled to appear on the program that was in progress, and thus frantic re-booking of the show had to take place behind the scenes. Further to that, McMahon now had a fragmented relationship with his reigning champion, a man he'd chosen to end the WrestleMania winning streak of The Undertaker less than one year prior. Thankfully, Lesnar and McMahon would settle their differences pretty quickly, and the man has since signed a big deal with WWE, committing his future to the McMahon empire. It can't have been a great atmosphere backstage at Raw that evening, that much is for sure!
