In which stories do the expressions "Oh my stars and little comets!"
and "Great howling crashwagons!" appear?

Is "Why don't you fade?" (good deeds, WDC 34, panel 1.4) an expression
invented by Barks? 

BTW. This story's first page belongs to my favourite Barks scenes in the
category "rolling on the floor laughing out loud".


Best wishes,
