Okay, I know of a guide horror story. John Wilson, a fantastic Arkansas fly fishing guide, was out one day with 3 clients (a crowded boat). There was a decent shad kill on the Norfork, and he had those folks tossing some big, weighted streamers in a strong crosswind. Unfortuntely, the weakest caster of the bunch was right next to him, and the wind was blowing from the fly fisherman to the guide.
As you may have guessed, the client double-hauled that big ole streamer with the heavy barbell eyes, and it slammed at full speed into the back of John's noggin'. The guide dropped to his knees in shock and pain. Apparently, he even shed a tear but didn't want to let on his anguish.
Years later, when I called this guide for something, I said, "This is Gil Lackey. You probably wouldn't remember me, but..."
John jumped in, "Oh, I remember you. I hadn't cried like that since I was a kid!" :D
