Phil "CM Punk" Brooks took part in a Q&A session in his home town of Chicago at the weekend and one fan was intent on challenging him to a fight.
The former WWE wrestler is yet to make his UFC debut since his controversial signing to the roster by Dana White last year, this has led to many UFC fighters challenging him to boost their profile.
However Punk immediately poked fun at the fan's challenge after he introduced himself by saying "you may remember me from Twitter",
No. You might remember me from Twitter is the greatest Troy McClure that the Simpsons never, ever used,
After laughingly engaging with the fan, Punk quickly grew tired of him. After saying that "I'll beat your sisters pussycat" the fan said that Punk was an "entertainer" and not a UFC fighter.
"I'm on the stage bitch, get the fuck out".
The session took place after the UFC on Fox 16 weigh-ins and was hosted by Megan Olivi.
UFC fighters clearly saw the altercation as no laughing matter as a Tweet from the fan revealed he's been kicked out of his gym.
Just got off the phone with @TWooodley he banned me from his gym. Good, I don't want to train with the losers of @UltimateFighter
