Direct references to Barks-stories

[Kai Saarto]

Hi fellow DCMLers,

I am looking for direct references to Barks-stories by other writers 
besides Rosa. I know that Van Horn referred to "Land Beneath Ground!" (W 
US 13-02) in his "Creature Comforts" (D 98062). I have tried to browse 
INDUCKS for more, but so far no banana. If anyone can remember other 
instances of this happening, this would be greatly appreciated.
