The golfer called to one of the caddies and said, “I want a caddy who can count and keep the score.”

“Yes, sir. I’m very good at keeping score.”

“We’ll see. If I shoot 3 on the first hole, 4 strokes on the second hole, and 5 on the third, what’s my score so far?” asked the golfer.

“Ten, sir,” said the caddy.

“Good, you’ll do perfectly.”
