A friend of mine took his wife to a baseball game, she knew nothing about the game, so he tried to explain the game to her as they watched. A batter hit's the ball and runs to first and my friend jumps up and shouts "RUN, RUN, RUN!!!" and his wife asked why the batter had to run. He explained that if the batter hit's the ball he has to get to first base before he gets thrown out. All was going well, the two of them enjoying the game, when one player got up to bat, several pitches were thrown, then the batter threw his bat towards the dugout and started walking to first base. My friends wife looked at him with a puzzled look and said, why is he walking to first base? My friend replied, because he has four balls, she jumped up all happy and shouted, strut you stud strut!
...I had a couple of minutes so I thought I'd sneak a post reply! :D
