News Anchors and on air emergencies?

Question

What do Newscasters do if they have some type of emergency while on air i.e. going to the bathroom, feelings sick on the stomach and they are taping live on the show? I've never seen one just get up and leave.

Answer 1

Going to the bathroom is generally something they should get done before the show.  Feeling sick is a whole different matter.  I've seen it once live.  The anchor had mentioned that she wasn't feeling great(Not on the air).  She motioned to her microphone when she was off camera and took it off as soon as the floor director told her it was dead.  The other anchor took over from there.

I don't think you'd ever see someone leave live on the air.  The show would go to something else first so that the person would be able to leave without disrupting it.  There are usually people there to take over if something happens.  

Answer 2

I saw a video already of a newscaster who was calmly giving the weather, and suddenly he makes a strange face and starts shrieking loudly--he sounded just like the stereotypical hysterical woman. They cut away from him, the shrieks still sounding in the background, and when they finally stopped, switched back over. Here a snake or giant bug or something had started crawling up his pant leg. The funniest thing was that while he was apologizing to the viewers and explaining what happened, it ran back up his leg and he started shrieking again.
