I used to work on a golf show or two. I'm rubbish at golf, but it did lead me to appreciate it. There was a story in the press about some punter going to an independent bookmaker and asking for the odds of a hole in one at whatever major tournament was on that week .... the Masters/ The Open whatever. The bookie didn't know his golf and gave pretty big odds, which the punter laid into heavily.
The punter knew that Holes in one are fairly common place at that level .... with say 4 par 3s per round, four rounds, and a hundred plus of the best golfers on the planet playing them. It's almost nailed on.
