Mark Watson continues his quest to improve the world.

As broadcast live in November 2011 - he invites the audience join in via tweets and messages to work out how we can all make the world a better place.

He's nimbly assisted by:

Tim Key
Tom Basden.

This time Mark looks at "Intelligence".

A certain amount of intelligence is pretty useful - but are we sometimes too smart for our own good? Without the ability to reflect and calculate, we would all be setting fire to our shoes and buying those novels about women who shop and have relationship issues.

Yet intelligence has been something of a curse to many. Galileo was tortured for knowing more about science than the church leaders, and Paxman sighs an awful lot when he's hosting University Challenge.

Producer: Lianne Coop.
