Seven-year-old Toby went with his mother to watch his teenage cousin, Jack, practice at a local karate club. Toby idolised Jack and constantly tried to mimic his style.
During the session, Toby watched through a glass viewing panel as Jack performed an intense routine on a large, weighted inflatable dummy. Jack kicked the dummy in the side while shouting "Hi-yah!", and then repeatedly struck it on the head with a foam noodle, yelling "Down you go, monster!" At the end of the demonstration, the instructor praised Jack, saying "Excellent intensity, Jack!"

Toby ran up to the alien, kicked it in the side while yelling "Hi-yah!", and then picked up a plastic toy spade and began striking the alien on its head, shouting "Down you go, monster!"
