Though also not a true one-liner, I always enjoyed Finn Aagaard describing his experiences with guiding hunters in Africa who didn't get a knock-down with their first shot. "In my typical fashion, I managed to put a bullet into the buffalo's hind end as he disappeared into the brush," or something on that order. I always think that Mr. Aagaard had perfected that shot during his guiding years!
You are correct that Finn had that shot perfected. He was accompaning a friend on a bear hunt with me and when the hunter wounded a bear and as it headed toward the nearest pucker brush Finn broke it's pelvis and anchored it so the hunter could finish it off.
