He ran away with his tampon in place and people still chant for him even though he's said he won't come back. That's like chanting for Jeff Jarrett to come back to WWE.
The difference is Punk needs WWE more than Jarrett ever did.
Punk makes himself out to be a rebel when, in reality, he's desperate for attention.
He's a mark for himself and enjoys passing his beliefs off as superior to everybody else.
Punk is intentionally sitting out because a) he loves the chants b) he'll come back as a beloved part timer c) he doesn't know how to use a gym
Jarrett makes lemonade out of lemons. Plain and simple. Give Punk lemons and he'll p*ss and moan about you giving him lemons.
