In what seemed to be a routine exercise in a youth karate class, one of the instructors was recorded working with a young girl to help her get out of an "attack." One little boy in the group across the gym, however, took this training session as a much more serious situation and began hobbling over in his gear to swiftly punch the instructor and give his friend a chance to escape.

Watch the video to see the adorable little guy protecting his friend – looks like those classes are paying off for him!
