I have no idea why Kieran thinks that this Dara Ó Briain video would be my cup of tea. We all know that I am devoted to the ideal of communicative reason between respectful parties speaking in good faith. None of that tawdry mockery and whacking at people with sticks for me, no sir. Nevertheless, it's quite charming; perhaps it's the Irish accent. Ó Briain studied math and theoretical physics at University College Dublin, where he was an officer of the Literary and Historical Society, where I spoke not too long ago. I cannot speculate where the fashion sense came from.
