Strange to say, this brief humorous piece is not Google-able: although I’m sure the piece is in a printed bibliography of Bradbury, the title is not to be found online. So, I figured, why not be the first person to put the bibliographic info online?
Probable first appearance in: FANTASCIENCE DIGEST, Jul-Aug-Sept. 1939.
Just a few paragraphs, with a high pun rate; Bradbury first describes Kuttner’s pet ghoul Oliver (whom Kuttner sent over to visit Bradbury), and then his own ghoul Moses Gable. Quite funny, and appropriately classified by the fanzine as “humor.”
