Martin Clunes and I are taking a break between filming scenes on Doc Martin – in which I play chemist Mrs Tishell – in Port Isaac, Cornwall. Among the mob of fans waiting patiently, cameras in hand, Martin spots a woman with an eccentric-looking spaniel.
'Aaah, hello,' he says, addressing the dog as an old friend. 'You've got lovely long ears.'
'Yes,' says its owner, 'when he gets anxious he chews them.' With a large dose of self-deprecation, Martin shoots back, 'Don't we all?'
