The Baseball Lesson

David from England is visiting his friend Stan in America. One of the first things Stan does is invite David to a baseball game. Soon after the game starts, the first player hits a single and runs to first base. The next batter is a dangerous batter, so they decide to walk him.

David is very confused to see this and says, "I don't understand what’s happening, Stan. Why did the first player run to first base, whereas this last one just walked to first base?"
"It’s really simple, David," says Stan. "That’s because he got a walk - he had four balls."

"Oh now I understand," says David. "That's enough to slow any man down!"
