His 'boyish wonder', although personally I think it's genuine, does get annoying to those of us who have their own wonder to contend with. Though, perhaps, those completely devoid of it themselves appreciate the cues.

I really don't mind Cox... what I despise is the trend of putting comedians in to science and politics shows in an attempt to relieve the dowdiness (Sorry Dara). Then again, I'm one of those people who used to sneak downstairs in the early hours to watch the dusty math and science stuff the BBC used to broadcast for teachers to record on VHS.
