Comedian Harry Hill weaves his live shows out of a seeming confetti of disparate threads, charming his audiences with unexpected callbacks to various themes, often offering surprise zingers to subtle set-ups that were funny enough in themselves before he seemingly left them along the way.  Initially, one might guess that Hill writes the sentences of his various comedic anecdotes and storylines onto cards and then shuffles them up to create a random mosaic, but we suggest that his technique is better described by a wholly different game: chess.  A chess game progresses as many very different pieces move in carefully calculated turns, some incrementally, some zigging and zagging and even changing direction.  But here's the real twist: Hill's comedic chess game is played in reverse.  He begins with his checkmate move, hooking the audience from the very get-go, and only when the show is complete does the grand arrangement of Hill's material reveal itself.  In the show "Harry Hill in Hooves" (2005), it's the knight piece that wins the game, as revealed when Harry makes his grand entrance by riding piggyback on someone in a funny horse costume.  (This entrance is actually a subtle visual joke in itself, as Hill often wears costumes that give the illusion of someone riding a beast, in which the animal's legs are in fact the performer's.  Here, he surprises the audience by leaping off the horse and proving that his own legs were not in fact the horse's.)  Hill's scripts, by design, are not decodable as highly structured until the very end, when the many pieces of his game board finally line up in the audience's minds, ready to be played forward in memory.
