One of the guys at work asked why I needed lessons after 15 years of riding, when he went on a trail ride and was shown how to ride in 5 minutes.
This guy happens to play golf. I said I knew how to golf: you put the ball on the grass, smack it with a club to see how close you get it to the hole.
He said I didn't know how to golf. I said " If you can ride, I can golf."
