Yesterday broadcaster Steve Martin tweeted "BBC colleagues - recreate the NBH experience at home by randomly changing the thermometer (thermostat) and releasing some pet mice".
A mouse you say? In the studio? Yes, unexpected rodent sightings did seem to be commonplace around the BBC and I've dug out audio evidence of a couple of incidences.
First, the now infamous mouse-related episode up at Media City in January 2013 during Shelagh Fogarty's 5 live show. As guest Mike Linnell spots the unwelcome intruder there are girlie screams from Shelagh as she hops onto her chair in a scene reminiscent of an old Tom and Jerry cartoon. "It's on the bloody table," she exclaims.
This all happened just a month after another mouse had popped up during Kate Kinsella's weather forecast, presumably from a London weather studio, during Iain Lee's BBC Three Counties morning show. This one is "quite sweet actually" as Kate rejects Iain's suggestion to despatch it with a book or a block of wood.
