If we see a class as a restaurant, your illustration makes sense. But
from my point of view, we don't know the name of the restaurant, nor
its menu. We just sit and cry for "Spaghetti!", and sometimes the
waiter says "I'm sorry".

But they never do seem to run out of chunky bacon.

The example translates to:
Restaurant := Class
Menucard := #methods
Say "we don't serve that" := raised Exception

If it changes from time to time I agree with you. But if it is "never",
the restaurant shouldn't put the menu on the card in the first time - in
my oppinion :)

My regards
