Mike Perry duets with Yoel Romero, $25K Roshambo and Jon Jones: Dirty Boxing Championship behind the scenes

Jon Jones, Mike Perry and Yoel Romero walk into a bar…

OK, so they didn’t walk into a bar, but while you’re imagining the wild scenarios that hypothetical situation would produce, those three unique personalities popularized in MMA were all present for the inaugural Dirty Boxing Championship at an “undisclosed location” in Florida.

Perry’s new fight promotion brings a unique set of boxing rules that allows for MMA elements such as ground-and-pound and elbows. The fights produced a number of wild finishes, including Romero’s devastating knockout in the main event.

Perhaps more interesting than what happened inside the custom Dirty Boxing Championship ring, is what went down behind the scenes. The private event’s guest list featured a number of familiar faces, including UFC heavyweight champ Jones, Paige VanZant, and many others.

In a behind-the-scenes video of the event, Perry was seen singing Gnarls Barkley’s “Crazy” with Romero, Jones oversaw a $25,000 Roshambo battle, and of course, video of the knockouts inside the ring along with the aftermath of the winning and losing sides.
