Cheap French philosophy

I've got a spare ticket to see Alain Badiou speaking on "The Passion for Inexistence" at the Jacques Derrida commemoration lecture Birkbeck College is hosting tomorrow. (Can't make it myself; events, dear boy, events.) Anyone who thinks sitting through an hour of postanalytical ultra-left French philosophy is a pleasant way to spend a Friday evening, email me and I'll devise a cunning plan to get the ticket to you.
