On golf:
"It's good sportsmanship not to pick up lost balls while they are still rolling." -Mark Twain
If you are afraid a full shot might reach the green while the group ahead are still putting, you have two options: you can immediately shank a lay-up, or you can wait until the green is clear and top a ball halfway there.
If your best shots are the practice swing and the "gimme Putt", you might wish to reconsider this game.
"Golf can best be defined as an endless series of tragedies obscured by the occasional miracle."
