Sherlock, Series 2

James Moriarty:
Hello. Are you ready for the story? This is the story of Sir Boast-a-lot. Sir Boast-a-lot was the bravest and cleverest knight at the round table, but soon the other knights began to grow tired of his stories about how brave he was and how many dragons he'd slain, and some of them began to wonder, "Are Sir Boast-a-lot's stories even true?" Oh no. So, one of the knights went to King Arthur and said, "I don't believe Sir Boast-a-lot's stories. He's just a big, old liar who makes things up to make himself look good." And then, even the king began to wonder, but that wasn't the end of Sir Boast-a-lot's problems. No. That wasn't the final problem. The end.
