The CM Punk versus John Cena feud was one of the best feuds of the past decade. Sort of like a Rock versus Austin for the PG Era (which sounds like a backhanded compliment, but it's not). Their match at 2011 Money In The Bank, the Pipe Bomb promo on Raw, Punk unexpectedly busting out a piledriver during a match. All of these moments ensured that nobody would forget their conflict. Sadly, after reading this sign, you can't help but feel like it was missing one thing to make it truly one of the best of all time. No, Punk didn't Muay Thai kick Cena so hard that he exploded into billions of Fruity Pebbles, but they still had great matches with one another despite it.
