YOU don't know about me without you have read a book by
the name of The Adventures of Tom Sawyer; but that 
ain't no matter. That book was made by Mr. Mark Twain,
and he told the truth, mainly. There was things which 
he stretched, but mainly he told the truth.  That is 
nothing. never seen anybody but lied one time or 
another, without it was Aunt Polly, or the widow, or 
maybe Mary. Aunt Polly--Tom's Aunt Polly, she is--and
Mary, and the Widow Douglas is all told about in that
book, which is mostly a true book, with some 
stretchers, as I said before.
