I used to believe my grandfather was the Scourge of the Seven Seas!
My father would tell me tales of his father's great adventures as a pirate; my grandfather was an amputee, and he had a "wooden leg," lending massive credibility (I was maybe 4) to these stories. One day, my grandfather had a gift for me: a bag of golden coins. Even after I discovered that they were chocolates I thought "wow, he *really is* a pirate!"
