One of the Captains I used to fly with a LONG time ago had a great sense of humor. One of the first times I flew with him he said, "You do the exterior preflight normally but I will do them when it gets real bad outside. Of course, I have yet to see it *real* bad..."
Truth was, he often did the walk-around when it was raining or snowing. I took a lesson from him and often did the exterior check...sometimes even when it was 'real bad'.
