#2: The Summer of Punk

In the summer of 2011, there was no wrestler on the planet more popular with CM Punk.
After cutting a scathing promo on the June 27, edition of RAW, Punk was on fire, after claiming he would leave the WWE with their WWE Championship. Doing just that at Money in the Bank, in Punk's hometown no less, the Second-City Savior would walk away from the WWE, for about eight days.

This shocking leaving with the title though was very similar to Punk doing the exact same thing years ago in Ring of Honor. As the ROH Champion in 2005, the future UFC star threated to leave that company with their title, when he went to WWE.
Debuting on ECW in 2006, Punk would have an incredible career, before walking away from wrestling in early-2014.
