Sam Clemens interviews Mark Twain" was an idea for a sketch that MT proposed in his journal near the end of his career. He never wrote that. But for a volume titled Lotos Leaves, edited by John Brougham and John Elderkin and issued in November, 1874, he did write this somewhat surreal sketch, about his own (non-existent) twin brother. This is his earliest rehearsal of the trope of changelings that he employs in both The Prince and the Pauper and Pudd'nhead Wilson. Later MT used versions of this "encounter" as part of his live performances.
