toilets (?!) in Duckburg

[Nils Lid Hjort]

Norwegian DD #49 is out on the streets today, with 
2nd episode of the Kalevala story and with a nice reprint 
of the Christmas 1953 issue (featuring Barks' "You Can't 
Guess" from Xmas Parade 1950). 

Upon browsing through the other stories I am moderately 
surprised by the little girl Wenche, in the "Ready for 
New Challenges" story by Pat & Carol McGreal and Esteban. 
She shouts to poor Donald: 
	"I need to go the loo! To the loo!
	 Now! now! I must, I must! Now!" 
A totally familiar situation in all civilisations, 
by all means -- but I thought going to the 
toilet/bathroom/restroom/loo/WC was on the predefined 
list of things never to be discussed in Disney's reports
from life in Duckburg? 

(a) Is there such a list, for Disney comics artists and 
    their publishers? (I've heard once that _fires_ are 
    not anymore to be discussed, for example. And surely
    aspects of sex and (real) death must be out of bounds.)
(b) Have their been earlier instances of or mentioning 
    of toilets in Disney comics?
