I would add watching your serious golfing partners reactions to bad shots.
I know, right? We all have fun, but some of the good golfer guys get pisses when they shank one.
Golfed with the same bunch of guys since we were young. My best was 128 (and I might have fudged that score a bit) but I once shot a legit 144 with only one ball. I'm very proud of that. And, believe it or not, I once won a golfing trophy. Best Dressed - I did the whole knickers, pompom hat and argyle sweater thing. Proud of that too.
