Was never shown on the show, but to you remember the episode where Frasier was going to meet with her at Cafe Nervosa to discuss saving her marrage with Niles? In that ep, Fasier waves to someone coming in... Is it Maris... a pale, thin lady in a scarf walks in and waves. It is Maris. No, she's waving to someone else. Marta (Maris' maid) walks in. Maris sent Marta in her place.
But let's take a look at the lady that walked in. Did you realize that this lady is the closest to Maris that the casting director could find? I just posted a pic of her on my group

lol yeah that sure looked like her too!!

Does anyone know the episode title on which Martin Crane
is excited about going to a doo wop concert with the
Orioles and the Teenagers? And, in which season did
it appear? Any help will be greatly appreciated.
