When Champ taunts Wes Mantooth about his mother and manages to break his composure, Ron Burgundy looks a bit disturbed and suggests leaving mothers out of it. In a deleted scene, it's revealed that Ron and Wes are maternal half-brothers (meaning that they have the same mother but different fathers), so Champ was insulting Ron's mother as well. It's also stated in the film as well, with Ron calling Wes Mantooth "brother" after he escapes the bear pit.
