In reply to tjdodd:
My favourite episode was the one where they were in a pub and Bob's doctor had him on his back on a table describing how he had to cut through his sternum and wrench his ribs apart to get at his heart. Must have been fun for anyone in the pub having their steak and chips
It is a great series - two old friends having a chat on a river bank. I love it. Even my somewhat cynical eldest daughter enjoys their gentle humour.
