Corrected entry: In the first of two episodes aired on August 22nd, a psychiatrist visits Shelley. He walks into the Rovers, greeted by Charlie and the others, and Charlie simply lets him go upstairs - without the psychiatrist showing any identification.
Corrected entry: 15th Dec '03 - In reference to a previous joke about christmas gifts, Katie was out shopping and saw a xylophone in the window (the gift Martin said that she definately wouldn't be getting him), but it was a glockenspiel in the shop, not a xylophone.
Correction: Many many people make that mistake of getting the two mixed up, she might not be very musically talented. Character mistake, but not a movie mistake.
Correction: It is very likely that Charlie had already seen the psychiatrist when he booked the appointment for Shelley.
