John Cena and Kane wrestled to a double countout during their match at Royal Rumble 2012. The action spilled to ringside and neither man was able to get back into the ring. Kane gave Cena some chair shots after the match, and then attacked an injured Zack Ryder as well.
"It was over a video game. Vince signed a contract with (Nintendo) and told me that I couldn't sign an endorsement deal with another company (Sega). I told Vince that he didn't own me; I wasn't working under a contract at that time."
