the M of A took the call but seems relatively unsympathetic at the moment

More marginal characters from episodes past hear about the new station.  VERY marginal.  Take Duncan here, who gets a quick offer from a tiny, unseen William or one of those DJ's

 Apparently, Duncan was yesterday, as today Bella appears having heard him in action the previous night.  The former Muse or was it Disney Princess refers to a character we may never recover, Wolfman Jane.  

 In this alternate account of her arrival (accounts vary), she refers not to radio WOBY but the very short-lived radio YAYA, and the legendary multi-dimensional corner offices the narrator somehow appended to the back of the coop. 

Comes last to the new Radio Station, last as he apparently was first.  With an AI name of Noah.  He wants to be the first to call the narrator by his new name - wait ...  Old Man Likert??  Now wait a second

And gives him a half an hour to learn how to yodel.  Have you got that?
