More to the point of the post, Sam said he had a 100 foot put at Turnberry once, playing with Don January. January supposedly marked his ball in the wrong location, but noticed it before he left the green, so it was a one stroke penalty. Snead said he had a 100 footer on the next hole, marked it on the lip, sunk it for three, and assessed himself a one stroke penalty.
Joe Black chimed in that it was that incident that got rule no. 1 amended - If it is technically true and legal by the rules, but not in the spirit of the game, it's not legal.
