Jon "Bones" Jones and Daniel Cormier appeared together at a press conference for their upcoming bout at UFC 178.
Apparently, they decided they'd go ahead and get after it. The video is right up there. Here's another angle.
Jones, the UFC light heavyweight champion, took to Twitter. It didn't take long for Cormier to respond.
