Batphone

Mark frequently frowns upon Simon's failure to turn off his mobile phone during the show. However, following a contribution direct from the Good Lady Professor Her Indoors, it was suggested that a phone should obtained as a hot-line to Simon, who will be the only person with the number for the Batphone. The Professor will use it to correct Dr K on anything, or to just chip in.

Mark's fear is that it will be going off the whole time.
