A bit of background needed, please bear with me.
Aged 15 I stuck on the telly one evening not knowing what was on just as the BBC2 logo faded out and a program started.
The scene showed a rocky beach late at night, not a sound except waves breaking. Out of the darkness came a small boat rowed by an authentic looking motley crew of smugglers who pulled the boat onto the beach and stood gazing up the beach in a state of tension. After a few moments a light shone from up the beach and, in total silence, the men set about unloading their cargo. As they carried barrels and boxes up the beach they passed behind a large rock on top of which was a large mahogany desk seated behind which was John Cleese in pin-stripe suit and brylcreem. He shuffled his papers, looked up and said, "And now for something completely different!"
I was so helpless with laughter that my mum and sisters came running in to see what the matter was.
