The Museum of Curiosity is the natural meeting place for entertaining experts and expert entertainers.

This week, it's flinging open its doors, inaugurating a brand new wing of empty plinths is ready to receive 3 new exhibits.

Our host is (as ever) the Professor of Ignorance, John Lloyd, and for this series he is joined by a new curator, the comedian Humphrey Ker. This week's generous donors are Egyptologist Prof. Joann Fletcher, who is presenting us with a hugely significant Roman coin; explorer Col. John Blashford-Snell, who brings a compass that led its owner the greatest one-liner in History; and the comedian Mark Watson, who is offering us something rather small and personal.

Produced by Richard Turner.
