Every year on this date I share a management tip for stations that get blindsided when somebody on a program you carry says the F-word before 10 PM.
If this happens, do nothing at first. Wait until you see whether the audience responds. If some dip-head does threaten to complain, tell them you are absolutely sure the F-word could not possibly have been said on your station because "YOU PREVIEW EVERY PROGRAM FOR COMPLIANCE." Bullshit, yes, but lying is an American freedom.
If you study 20 psychology books, a total of 20,700 pages, somewhere in there it says that "human memory tends to slip and shift so that people become unsure of what really happened in the past."
As long as you are moralistically righteous and stick with your story, the caller will melt away in a pool of uncertainty about what actually happened.
The ALPB is the answer.
There's a video making it's rounds where on some popular tv talk show (I forget which) the subject concerns bullying in school.. and this little girl about 12 I guess uses the "C" word twice during the interview!.. "Because she called me a c---"
edit..
It was on the Today Show!.. She said it twice but apparently the censors missed it, but Meridith didn't and told the girl she couldn't use that word on tv.
