Geraldo Rivera Threatens Co-Host While On FoxNews Set [VIDEO]

FoxNews co-hosts nearly came to blows while discussing immigration on the show "The Five." 

When one co-host accuses Geraldo Rivera of sensationalizing stories, he nearly goes CRAZY!!  Geraldo, who we know can get quiet emotional at times, told the guy next to him that if they were not friends he'd "knock him out."

You can hear in both of their voices that this was not scripted and that certain strings had been pulled. Luckily, the host calls a timeout and asks production to go to a break.

I'd love to have seen what went on during the break. I have a feeling that one, if not both of the men, left the desk to compose themselves.

Who do you think would win this fight if the two went at it? I must admit, Geraldo seems to have A LOT of aggression inside of him.
