Joining John Lloyd and new curator Sarah Millican this week are comedian Holly Walsh, the author and adventurer David Bramwell and "Freakonomist" Stephen J. Dubner.

Holly Walsh, a comedian who made her debut on TV at the age of six as a badger enthusiast, and who later appeared on Celebrity Mastermind with her specialist being "badgers", donates to the museum The Vows of the Peacock, a medieval poem which features strange illustrations, including people with fingers up their arseholes, and naked women riding giant phalluses with smiley faces on them.

One-man cottage industry David Bramwell, a man who has met people from all kinds of alternative backgrounds, from anarchist societies to a utopian society in Arizona, offers the part of a time machine, taken from an Italian community the Federation of Damanhur, who made an underground temple.

Stephen J. Dubner, co-author of Freakonomics, who has helped to proved the drunk walking is more dangerous the drunk driving, and who believes we should abolish the penny, gives The Museum of Curiosity a microchip that could be implanted into a brain that could read human thoughts, even though Dubner hates the idea of it.
