On the subject of convincing the gullible of untrue things, a mate of mine once convinced another kid that his uncle was the hand inside Edd The Duck. Also, that the reason he had slightly slanty eyes was because he was born while his parents were on a walking tour of China. However, I can't really gloat because I was once convinced by my sister that she was the girl on the BBC test card playing noughts and crosses. And I believed for a whole term that Howard Maxwell's middle name was Oermantrudie. It was actually Oakley.
