#1 Mr. McMahon blows his quads while entering the ring
This moment from early 2005 saw two back-to-back instances where things didn't turn out the way they were planned. The 2005 Royal Rumble match ended with John Cena and Batista both hitting the floor at the same time. Originally, Batista was supposed to cling on to the ropes and win the annual free-for-all, but things didn't end that way. Vince McMahon came strutting to the ring, as several RAW and SmackDown referees were arguing over who had won the match. Vince rushed to the ring and as soon as he entered, he collapsed. Vince still didn't break character and sat down beside the ropes, as the referees talked with him.
A furious Vince stated that the match would be restarted, with Cena and Batista fighting again to determine the winner. Soon after, Batista eliminated Cena to become the 2005 Royal Rumble winner. Vince somehow managed to get to the back without any help, even after tearing both of his quads.
