"But in the final episode of this series , Martin was driving a motorboat and i was on the side, firing at the baddies. We were whizzing along when he turned a corner and i fell overboard. The trouble was that my foot caught under a seat. I hit the water at about 45 knots and was dragged along underwater.
Martin was looking the other way and the crew on the other boat was screaming at him . He thought they were waving and carried on. It was only about 30 seconds but i thought i was finished. When i got out i said to Martin , Listen mate, i know it's the last episode but i'd like to come out of it alive "
