found the airdate of the episode I have been desperately trying to obtain, it is September 14, 1987. Episode 6561D.
It definately was a Janice-Holly-Dian episode and all I can remember was that Janice and/or Holly were modeling an item up for bids like encyclopedias or something and they were wearing glasses.
From the audience view I was sitting on the right side, center, about the third or fourth row in.
If anyone here can help me I would truly appreciate it.
Thanks-
Marco
