College roommate reveals Jon Jones' violent past: 'He'd be throwing people through windows and stuff, it was nuts'

Ultimate Fighting Championship (UFC) light heavyweight kingpin Jon Jones is perhaps the greatest mixed martial arts (MMA) fighter in the game today, racking up an impressive 20-1 record with 15 violent finishes.

Turns out he had plenty of practice.

His old college roommate and former wrestling buddy Colby Covington has given fight fans a glimpse of what "Bones" was like in his younger days, and let's just say it was a rough couple of years for the "townies."

From the MMA Roasted podcast (via FOX Sports):

"We got into a lot of trouble. When you're in a small town in Iowa, a lot of kids are farm kids and they always wanted to start some stuff with the wrestlers and I was a national champ in college and Jon was a national champ, so they'd always try to pick fights at our house parties and stuff. We would just clear out the place of a bunch of townies. Especially Jon -- he'd be throwing people through windows and stuff. It was nuts. He has a bad temper, when he gets mad -- he gets mad."

Have a listen:

Hey pussy, are you still there?

If so, make sure you watch Jones try to treat Daniel Cormier like a drunken farm kid at the UFC 182 pay-per-view (PPV) event on Jan. 3, 2015 at MGM Grand Garden Arena in Las Vegas, Nevada (more on that here).

Fortunately, there are no windows inside the Octagon.
