Hate to hear your hosts interrupt each other & your guests. Turn off the program when this happens. Everybody thinks what they have to say is more important than whoever is currently speaking. Justifying this behavior due to time restraints is simply justifying the rude and ego driven behavior. If time restraints are real, then give your guests a system to know when to stop or wrap up their point. Visual cues such as red, yellow or green lights. Interrupting each other as hosts is frustrating for viewers and unpleasant to watch.
