One of these stories is called The Turkey Prince. You can find the story at the link, of course, but I'll put my own telling of it here:
There was once a prince who suddenly, out of the blue, declared that he was a turkey. He took off all his clothes, went under the table and began to peck at the crumbs. No one could understand why or convince him he was actually a prince and ask him to come out from under the table.
