Can anyone tell me what the capital city of Ork is? I've heard that it is either Cork or Frizbatt. Please settle this argument! Thanks

It's Kork

"Well, Laverne is sort of childish"

"Childish? Childish? COming from a grown woman who throws tea parties for her stuffed cat!"

"Well at least I don't sew L's on everything I wear!"

"Well that would be pretty stupid considering your name's Shirley!"

I read in a trivia book and in several places of the internet that it is Kork, though not spelled C-o-r-k like the city in Ireland. The Trivial Pursuit Genus II Edition and several OTHER places on the internet state that it's Frizbatt. I remember an episode in which Mork states that a picture from Ork is of "Frizbatt, the capital" and
when Fred says he can't see anything, Mork replies, "It's the inner
city." I do not recall any episode on which it was stated that Kork was the capital, but if anyone can I would be interested in reading
about it in as much detail as possible.
