Host Sara Pascoe is joined by comedians Nish Kumar, Natasia Demetriou & Tom Allen who compete to deliver the best lecture.

Nish's lecture is ‘10 Ways the World Could End', Natasia's is ‘Anatomy of the Vagina' and Tom's is ‘Why We Make Bad Decisions'.

All three lectures are judged by an expert and then the audience help decide the winner by voting for their favourite lecture.
