Alexander Armstrong and Richard Osman are joined by various writers as they attempt to win money for charity with obscure knowledge. Among those competing are Richard Stilgoe and Don Black, who have both been on before and done well. The former got through to the final while the latter won the jackpot. Also taking part are Richard Madeley and Dreda Say Mitchell, John O’Farrell and Lise Mayer, and Jenny Colgan and Jane Fallon. You can also expect to see quite a few good scores when the writers come to a round about words. Pointless Celebrities is on BBC One at 18.10.
