The Last Thousand Dragons. Children's audio story narrated in British English.

There are many legends dealing with the extinction of dragons, but only one of them involves a certain Sir Emile, a brave knight who finished off the last thousand dragons. Like many others, Sir Emile spent years studying the cruel and wicked behaviour of the dragons of his time. However, his own particular conclusions were unique and unusual: dragons lived in a constant state of anger, which created the fire that came from their mouths.

So, when he decided to finish the dragons off, he swapped the normal weapons and armour of a knight for something rather unusual: a joke and a cart full of ice creams. When the first dragon came to eat him, Sir Emile shouted his joke at it. It was such a good joke that even the dragon had to laugh. Just as the brave knight had expected, this blew the dragon's fire out. Just as the dragon was laughing, Sir Emile offered it an ice cream...

How refreshed and pleasant the dragon now felt, after years of having had a fiery throat! Taking advantage of the dragon having calmed down for a moment, Sir Emile offered it a piece of fruit, and to the dragon this tasted heavenly.

Dragons didn't normally eat fruit or vegetables, because the fire of their mouths burned such food and left it without any taste. So they preferred to eat cows or people, which, even though left a bit singed, at least tasted of something. However, when the dragon tasted fresh fruit for the first time, it felt so happy and joyful that even its terrible appearance began to change. It had looked so bad because of its awful diet, but after only a few days of this new, healthier, life, the dragon disappeared one night. All that remained of it was a beautiful butterfly with large colourful wings...

And so it was, that Sir Emile, using only some good jokes and a cart full of ice cream and fruit, made the last thousand dragons disappear and take up new life in the form of beautiful butterflies.
