Last summer, a heel Punk cut a promo about winning the WWE Championship and leaving the company as his contract expired the night after the Money in the Bank pay-per-view. During that promo, he called himself for the first time, "The Best in the World." He won the title, left, returned a week later, now a babyface, with "Best in the World" becoming a catchphrase. He began his second title reign in November at Survivor Series in Madison Square Garden and continues to hold the championship. Shortly after, vignettes began airing teasing the return of Jericho, who during his last run, called himself the "Best in the World At What I Do." Jericho returned on the first Raw of 2012. He was silient for several weeks, "trolling" the audience, until he revealed that he came back to rid the WWE of Chris Jericho wannabes like CM Punk. During the Elimination Chamber PPV, Jericho was one of five challengers to Punk, but was eliminated without being pinned when Punk kicked him in the head and out of the cage, knocking him unconscious (in storyline). Jericho won a battle royal the next night on Raw to challenge for Punk's championship at WrestleMania. While the feud was initially based on who was the "Best in the World," Jericho introduced a new element - Punk's straight-edge lifestyle, which he said was born out of Punk's father being an alcoholic and his sister being a drug-addict - to make the feud more personal.
