Rider
After a round of golf, four ladies sat around the club house, chatting.
Seeing the ladies, the Pro approached them and asked: "How did your game go?
The first lady, a brunette, said she had a good round ... making the comment that she actually had 25 riders. The Pro was a bit perplexed not knowing what a "Rider" was.
The second was a blonde lady who quickly chimed in and said that she had a very good round as well with 16 riders.
The third lady then said that her round was average and that she only had 10 riders.
The fourth lady admitted that she played the worst round of the day and that she only had 2 riders all day long.
The Pro was completely confused not knowing what the term "rider" meant. But, because he didn't want to look dumb, he made a quick polite remark, wished the ladies well and then left.
He then approached the bartender and asked "Hey, can you tell me what these ladies are talking about when they refer to "Riders"?"
The bartender simply smiled and said..."A 'Rider" is when you hit a shot long enough to ride on the golf cart to your ball.
