My guess is that #3 was a classroom and not a broadcast operation.   While they hire young at local stations, the anchors and sportscaster seem unusually young and green. I cannot fathom ANY station hiring someone who be that unprepared to handle an emergency. I also doubt that any director would allow the segment to go on like that for four minutes without wrapping early and going to break or something else.   It had the appearances of someone being given practice and coaching.

#2 is priceless!!!!   I have witnessed similar events, but NEVER on camera like that.   Both should have been fired on the spot!
