A colleague pointed me at yesterday's Start the Week on Radio Four. This week, it's four historians arguing about World War II.
He described it as being like Newman and Baddiel's History Professors, who act roughly as follows:
Prof1: This is your book.
*takes a copy of Prof2's book and sniffs the pages*
Prof1: It smells of poo.
It really is. And it's utterly hilarious.
