#2. CM Punk - Backstage
CM Punk was the self-proclaimed "Best in the World" during his time in WWE before he left the company back in 2014.
Many of the WWE Universe thought that CM Punk made his official debut back in 2006 as part of the ECW roster when it was rebranded under the WWE banner, but Punk actually made his first appearance on WWE TV a number of years before.
CM Punk appeared in a backstage segment alongside Mr Kennedy and Brock Lesnar as a fan of The Beast Incarnate who was attempting to congratulate the new Champion following his victory over Chris Benoit at WrestleMania XIX. Punk was seen shaking Brock's hand before he moved over to sign the chest of a female fan.
Punk later appeared as part of John Cena's WrestleMania 22 entrance where he was one of the gangsters, a few months before he made his ECW debut in June 2006.
