WWE Backstage analyst CM Punk on Tuesday posted a tweet saying he was feeling weird to catch up on what has happened over the last five years. The former World Wrestling Entertainment (WWE) champion also added in the tweet that he is going to talk about a lot of things on the upcoming edition of WWE Backstage.

He received a response from Former Universal Champion Seth Rollins, who asked CM Punk to stop talking and fight him instead.

After being away from the WWE for nearly six years, CM Punk made an unannounced appearance on an episode of "WWE Backstage", FS1’s new weekly studio show. During the final moments of the show, he entered with the Living Colour’s “Cult of Personality" being played on the background — Punk's entrance music during his WWE career.

While a lot of fans had given hope on watching CM Punk ever on WWE, his return turned out to be huge news. "It’s as simple as this: Just when they think they’ve got the answers, I change the culture,” Punk told the camera, before adding, "I’ll see you here next week."

One of the first ones to react was Seth Rollins, who tweeted to CM Punk, "Fight me @CMPunk."

Even though Punk is back working with WWE, his contract is just with FOX Network's WWE Backstage. But, the WWE Universe sees this as Punk's first step toward his ring return.

Punk left the WWE company on a sour note after his loss in the Royal Rumble 2014 match to Batista. For a while, Punk did not talk much about his exit before he finally spoke about it months later in an episode of "Art of Wrestling", hosted by his best friend at the time, Colt Cabana.

Earlier, when WWE Vice President Triple H was asked about Punk's return, the former had insisted that he was open for business with him. "That's a 'could be'. Vince will say it all the time: 'We're open for business'. The past is passed, today is today and you never say never in WWE," Triple H added.
