Professor of Ignorance John Lloyd and his curator Sarah Millican welcome:

* An award-winning Australian comedian who is so much more than a mere joker, Felicity Ward

* The cricket commentator whose association with James Bond villainy is more than a mere coincidence, Henry Blofeld

* A former chemist from Mars who is more than a Mir astronaut, Dr Helen Sharman OBE

The Museum's guests discuss the cultural significance of Australians using watermelons as hats; how you can increase your stature in more ways than one by going into space; how it took an author as inventive as PG Wodehouse to coin the word 'gruntled' decades after the word 'disgruntled'; the vital importance of toilets; and the coolest possible way of telling mountain trekkers where you were when you first saw the Himalayas.

Researchers: Anne Miller and Molly Oldfield of QI.

Producers: Richard Turner and James Harkin.

A BBC Radio Comedy production for BBC Radio 4 first broadcast in January 2016.
