This video, from the 1940s, is VERY fast, but you can still get the main points and see the humor in it. You don't even have to understand the topic, which is
baseball. All you have to understand that they are talking about strange "nicknames".
One man is named "Who". He plays "first base". The second
man is named "What". He is on "second base". Finally, "I Don't Know" is on third base. Later, we have "Why" and
"Because" playing next to each other. Finally, "Tomorrow" and "Today" are throwing and catching the ball.
In our next lesson, we will look at a modern version of "Who's on first?".
