Qualm with apartment #
Edit: thanks for the explanations guys!
I noticed something about Frasiers and Cams apartment numbers.
I don't recall which episode but Frasier is having a party that no one wants to come to. It might be season 9 episode 6: Room full of heros.
No one wants to come to Frasiers party and Martin makes a comment that "Crane party 1901" doesn't sound as exciting as Cams party in 2000.
If Cam is directly above Frasier with the same exact apartment and layout wouldn't his apartment number be 2001? There's probably an explanation but I'm not sure what it would be. Any thoughts?
