Agnes Brown

Agnes Brown was in attendance at a Christmas party with a host of other guests that included the Eleventh Doctor, Amy Pond, and a Cyberman. (TV: Consider Yourself One Of Us...)

Another Christmas, whilst Sarah Alexander and Rob Brydon were organising the BBC's Christmas shows, Agnes entered the Doctor's TARDIS, mistaking it for a dressing room that she hoped would be "bigger than it [looked]", before it dematerialised, taking her with it. She later returned, and assured a flustered Rob that she had been to the future and that their preparations turn out alright. (TV: It's Showtime)

Behind the scenes
Agnes is the titular character of the BBC sitcom, Mrs. Brown's Boys.
