[Neil Jones]

I assume this is partly why some programmes now state "Correct at time of recording" in the credits. Similarly questions often use "...as of month and/or year..." to cover themselves for being repeated. Pointless is an example that springs to mind as a programme which does both.

Back in the 80s the chance of a repeat years down the line was probably so small you literally had questions come up like "Who is the current Foreign Secretary?", which is an actual example because they used that and similar on episodes of Bullseye, although as it turned out there's only four possible answers for that question anyway if you can work out how old the repeat is.

They did eventually change that and started the whole "Who ate all the pies in February 1991?" thing.
