I once read a short story, quite convinced at the moment that it was by O. Henry, in which a grandfather figure sits down on his porch with a young boy and starts to tell him a story ... about a grandfather figure who sat down on his porch with a young boy to tell him a story ... about a grandfather figure who sat down on his porch with a young boy to tell him a story ... and on and on it went, several layers deep into a story that never went anywhere. The quotation marks alone ended up being:
"""""""Well, let me tell you a story," said the old man"""""
... because it was a quote of a quote of a quote of a quote of a quote.
And now I can't find that story anywhere. Any help at all is appreciated, especially if I have the entirely wrong author.
