Many years ago, a teaching colleague of mine got asked at short notice to cover for an absent presenter on BBC Radio Sheffield. He assumed that the producer would have chosen the records in advance and only found out just as the programme was going on air that he had to choose them himself. So he bunged on a track that he knew to be OK for the show and hurriedly started working out what to play for the rest of it. In doing so, he let the album run into the next two tracks. It was only then that he noticed the sticker on the album cover, stating that (because of the foul language) it was totally prohibited to play tracks 2 and 3 on air ;-)
