The Brothers Hitchens

Christopher and Peter Hitchens (both brothers, and both political commentators) met on stage at the Hay literary festival in Britain to argue about politics and attempt a public reconciliation after not speaking to each other for four years.
Peter and Christopher are alternate-universe versions of the other. Christopher is left-wing and pro-war, for instance, while Peter is right-wing and anti-war. Peter is almost laughably opposite Christopher; he positively delights in calling himself a reactionary.
They both speak off the tops of their heads in fully formed paragraphs. And, both being Hitchens’, the event is a fun ride no matter which of the two you prefer. The Guardian has the transcript.
