Please do not go to a Q&A session and challenge a professional fighter.

Former WWE World Heavyweight champion CM Punk, who is yet to make his MMA debut under the UFC banner, got into a little altercation this past weekend with a delusional and disrespectful fan.

UFC on FOX 16: Dillashaw vs. Barao 2 took place last Saturday night from inside United Center in Chicago, IL, and before the festivities commenced,  the polarizing athlete took part in a Q&A session with UFC fans. It's safe to say the moron seen above in this video brings out the worst in sports fans, and it's a shame Punk didn't confront the fan himself and show the world what he's been working on at Roufusport.

Still, Punk's mic skills are as good as ever.
