Pointless

Pointless was a show that Graham O'Brien was keen to watch. (PROSE: The Good Doctor) Jack Harkness stated, perhaps jokingly, that Pointless was on when he suggested that the Sixth Doctor watch television as he recovered from regenerative collapse within his TARDIS. (AUDIO: Piece of Mind)

Behind the scenes
Pointless is a British gameshow hosted by Alexander Armstrong. A Doctor Who edition of Pointless Celebrities, in which past Doctor Who actors took part, aired in 2013.

Graham being a fan of the series, as revealed in the above story, could been seen as ironic, as Bradley Walsh, who plays Graham, is the host of rival gameshow The Chase, which is typically broadcast on weekday evenings opposite Pointless on BBC One's rival network, ITV.
