Swap the 19th and 1st holes. Anyone who can still stand after, say two to three hours in the bar, is welcome to tee off.
In fact. They're welcome to f*** off. Because they're obviously not trying hard enough.
Come to think of it. This principle could be applied to other, extremely boring past-times. I refuse to call golf a sport.
Formula 1. Tennis. Snooker. Gymnastics. Eventing. Anything American. In fact, anything foreign. Cricket, obviously.
Darts, automatically. Though again, darts is NOT a sport.
