Most of us rather like it when something unexpected happens during a live TV broadcast. There's surely a little anarchy in everyone. Don't we rather enjoy those idiots in the background jumping up and down, waving at the camera or pulling silly faces? Often their antics are in direct contrast to the serious content of the broadcast.
I don't know if you've seen the clip below shown on the BBC lunchtime news last year when an American tourist from Canton, Georgia tripped during his walking tour of the City of Westminster. Passers-by helped this confused old gentleman to his feet and sat him on a wall. They asked him what his name was but at first all he could remember was that it rhymed with "vague". Fortunately, he recovered quickly and returned to his homeland with a handsome tale to tell.
