Pumpernickel an old Bavarian term for "hard", either referring to the process used to grind the grain into flour, or the density of the final bread product. According to "Langenscheidts Taschen Wörterbücher" (1956), it refers to a form of "pumping work". The philologist Johann Christoph Adelung states that the word has an origin in the Germanic vernacular where was a New High German synonym for being flatulent, and was a form of the name Nicholas, commonly associated with a goblin or devil (e.g. "Old Nick", a familiar name for Satan), or more generally for a malevolent spirit or demon. Hence, "pumpernickel"
The Scarlet Pumpernickel "J.L." - called "The Scarlet Pumpernickel", which he wrote himself (under the name "Daffy Dumas Duck.") As Daffy reads the script to J.L., the cartoon cuts away to various scenes and then back to J.L.'s office. Each time, Daffy announces a page number. By the cartoon's end, the script has exceeded 2,000 pages (movie scripts much in excess of 100 pages were usually rejected as too long back in those days). In this script, the clumsy Scarlet Pumpernickel (Daffy) constantly outsmarts the Lord High Chamberlain's (Porky Pig) men, to the Chamberlain's fury and the delight of the Fair Lady Melissa.
