Several sitcoms banned by Mastermind

Contestants on the BBC quiz show Mastermind will no longer be allowed to pick Fawlty Towers, Blackadder or Roald Dahl as their specialist subjects as the producers have run out of questions. Mark Helsby, Mastermind's producer, has revealed that some subjects are so popular that they have been "exhausted" for new questions. Father Ted and the Chronicles of Narnia have also been removed.
