My favourite Martin Jarvis moment is in the Inspector Frost episode Fun Time for Swingers.

Jarvis plays this out of work actor/gigolo. He has been beaten up. He goes off to meet a policewoman who is who is a set up - posing as a client.

With a raise of his eyebrows Jarvis indicates and explains his bruised face, and says....'The slings and arrows of out-rageous fortune.....'.

Whatever insoucianct means - Jarvis absolutely nails it. He does it so beautifully and with such humour, I couldn't help but wonder if it were in the script - or if it were a line he had contributed.
