I used to do live subtitles for a living. With live subtitlers that wouldn't have happened, but I guess a machine got stuck.

What happens when you have real people on the job is that someone sets their shortforms (acronyms that expand when you type them into the software, e.g. typing 'pcon' will automatically expand to 'press conference') for a serious documentary and then forgets to change them for the football report. Resulting in three minutes of 'Liverpool FEMALE CIRCUMCISION vs Manchester United', for the edification of the nation's deaf and second-language viewers.
