Be careful what you say on and off the air! UFC fighters, Jon Jones, 27, and Daniel Cormier, 35, went on live television to talk about their Aug. 4 brawl on ESPN's SportsCenter. However, after the interview was over, Jon and Daniel were still going at it. You have to check out the video, but be warned that the language may not be suitable for all viewers.

Jon and Daniel can't seem to let their feud go. Long after the SportsCenter interview to promote their Sept. 27 UFC 178 fight ended, Jon decided to reignite the intense squabble with Daniel.

"Hey [expletive], are you still there?" Jon taunted Daniel.

"I'm here," Daniel taunted. "You are just the fakest person! I actually admire that you can be this fake and when the TV comes on you can just change. You're like a chameleon! It's awesome! It's unbelievable!"

The two continued to exchange heated barbs at one another, Daniel even called Jon the "scum of the earth" and a "terrible human being."

Daniel wished they would let him next door so he could spit in Jon's face. That's when things got really serious.

"You know I would absolutely kill you if you ever did something like that," Jon replied. Daniel said that could never happen and Jon continued on.

"I would literally kill you if you spit in my face. Literally kill you. I'm not saying I would fight you, I'm saying I would kill you if you did some stupid sh*t like that."

Sounds like these guys have some serious beef. It's all leading up to an epic showdown on Sept. 27.
