In this Pudsey Special, two teams of clever celebrities prepare to lose their dignity in honour of Children in Need. The cunning wiles of the Great Believers 'Nick Hornby, Dame Joan Bakewell and John Lloyd' take on the combined brains of the Free Speakers (Ian Hislop, Simon Singh and John Sessions). So join Victoria if you want to know what connects Erte, Herge, Jeep and Esso.
