The humour may have been mis-judged, but resorting to violence is not on, especially in front of such a big audience. It sets a very bad example. Will had the chance to be the better man and still make Chris look bad. He blew it. I bet others there were not happy about this getting the headlines rather than their achievements.
there is a possibility that the whole thing was staged. Who knows?
I've seen people saying that. We really can't know.
