Video: CM Punk confronts Twitter stalker at UFC Q&A session

It's pretty easy to talk tough from the back of the room

Aspiring UFC star CM Punk's arrival with the promotion has rubbed plenty of MMA purists up the wrong way and there has been no shortage of fighters calling for a fight with the former pro wrestler. Now Punk is getting challenged from members of the public as well, after a Q&A session ahead of Saturday's UFC event in is home town of Chicago went off the rails. Punk was confronted by a man named Dillon 'Trouble' Pousson, who came to the mic to claim he had been calling out Punk on Twitter and wondering if his target was running scared. Aside from a lovely Simpsons Troy McClure putdown from Punk, the conversation got personal as Pousson invoked Punk's sister before his mic finally got shut down amid a chorus of boos from the crowd. https://www.youtube.com/watch?v=7gBcWO8iQRU [h/t Uproxx]
