Daffy Duck's full name is listed on the script as "Daffy Dumas Duck." "Dumas" is the surname of two authors (Alexandre Dumas, Pere, and Alexandre Dumas, Fils) of nineteenth century novels used as the bases for swashbuckling films, so this may merely be a reference to the father and son, and not Daffy's actual middle name.
