A Rider

A foursome of elderly gentlemen went to the bar after a round of golf
where the new Pro asked them "How did your game go today?"

The first said he had a good round with 25 riders. The second said he did OK with 16 riders. The third said not too bad since I had 10 riders.
The fourth was disappointed and said that he played badly with only two riders.

The Pro was confounded by this term "rider" but not wanting to show his ignorance just smiled and wish them better golf the next time. He then approached Jerry the bartender and asked "Can you tell me what does this term 'riders' mean?"

He smiled and explained that a "rider" is when you have hit a shot long enough
to take a ride on a golf cart.
