Every time we have a football class, some of our energetic boys have to move the football box.
The football box is full of baskets of football.
Every time I say, "sprint 100 meters!"
One of the strong boys said, "Oh, it's going to turn around!"
I said, "turn around and sprint 100 meters!"
Suddenly, a burst of laughter.
I think I have to think of other ways to tickle them in the future.
