I love finding clips of when things go wrong in broadcasting. (Maybe because I've been there/done that too.) It's always interesting to find out how the voices and faces handle it when things go wrong.
One of the funniest, and creepiest, "whoops!" moments I've found is this, from a night in 1978 when part of a miniseries was shown out of sequence. (I say "creepy" because it always scared me as a kid when a program was interrupted like that.) Notice how Howard Reig handles the explanation, too. This particular "oops" is a minor legend.
Then there's beloved Uncle Bob Schieffer having an "oops" moment, and hilarity ensues. Notice, too, how Bill Gilliand does the time check with a bit of a smile in his voice. (By the way, have you noticed that since the demise of the staff announcer, the world just isn't quite right any more?)
Of course, hands-down, this is my all-time favorite, as I've said on here before. I would only hope that if something similar ever happened to me, I'd handle it with that kind of cool wit.
