"Six Charlies in Search of An Author" is an episode of the British radio comedy, The Goon Show.
While the plot revolves around the common scenario of Neddie Seagoon being blackmailed by Hercules Grytpype-Thynne and Count Jim Moriarty, its development appears to blur the lines between the writer and the characters.
Neddie and Bloodnok are surprised at gunpoint by Moriarty and Grytpype-Thynne, who had played a recording of an explosion "written in without the author's knowledge".
Bluebottle, playing with the typewriter, imagines an attack by "Black Claw and his Chinese pirates", ruining their pursuit of the villains.
Reaching the banks of the river, they encounter Henry Crun, who tells them "Someone gave Min a typewriter and here I am!"
