The Fat Man based on a character created by Dashiel Hammett (1946 - 51)
There he goes into that drugstore … he's stepping on the scale. Weight? …

The Fat Mannnnn ….

The Fat Man character was Brad Runyan, played by Jack Scott Smart who gave an excellent lighthearted performance. The series made good use of author Dashiel Hammett's name, although the author had little to do with the radio series. The name The Fat Man was the title of a chapter in the book A Maltese Falcon.
