Random Riddle: Boys In The Park

A man is walking through the park one day and sees a group of four boys standing in a circle. A smaller boy is holding a large stick and hands it to a larger boy saying “I couldn’t do it, your turn.”

The larger boy swings the stick twice and the other two boys go to the ground. The smaller boy says “I’ll get ’em next time.” The man walks away smiling.

What just happened?
