John Lloyd and Sarah Millican this week are joined by comic Felicity Ward, cricket commentator Henry Blofeld, and the first Briton in space Helen Sharman.

Henry Blofeld, one of the presents of Test Match Special and former cricket player himself who almost played for England, donates to the Museum PG Wodehouse, one of the world's funniest novelists, wrote over 100 books, writing each book three times before the final draft.

Helen Sharman, a former chemist working at for Mars Bars, who later went on to become the first Briton in space after hearing an advert on the radio, offers up the Deep Space Climate Observatory, which takes full colour photos of Earth every few hours.

Felicity Ward, an Australian actor and stand-up comedian, and who has starred in The Inbetweeners 2 and made documentaries about mental health, provides the Museum with something rather simple, and the thing she has the longest standing relationship with - a toilet.
