Are You a Leprechaun?

Jonathan Mitchell meets the chosen one in Yaya's garden. Is he human? Are you a leprechaun? Three if I was wouldn't it be? In this part of the world? What are you then? Not from this world. Oh, I'm- I'm very much in your debt. You good-hearted men. If only they were a hundred more like you, this world would be nothing but a good place. Jonathan Mitchell: The Man Who Knew Too Much is on BBC1 at 9pm tonight.
