Disney-comics digest #296.

[Mark Semich]

Done Rosa wrote that any McDuck name like "Pothole", "Swamphole",
"Quagmire", or "Seafoam" must be a nickname.  I think that Barks
originally intended these names to just be funny names.  If their
departure from "real-world" names means that they must be nicknames,
then using the same logic, how could "Scrooge" not be a nickname?  Who
in their right mind would ever name their son "Scrooge?"
