I was probably 3rd grade when the movie came out. Wanted to take karate classes sooo bad, but was not allowed to. I'm appreciative now that I never held a big grudge about that.
My long time rival on the playground, who was at least as athletic at kickball, and with whom I competed for the hearts of girls since we were in the first grade, did sign up for karate and took it for years.
In the first grade he and I both loved the same beautiful girl, and she loved him, not me. I was so jealous that when the girl's older brother told me to punch my rival after school, I gladly did it. I sucker punched him right in the face. Then as my rival cried, the girl's older brother told her that he had told me to do it, so I didn't look like a total dirt bag.
So a couple years later, when my rival started taking karate and I didn't, I was pretty nervous about him eventually kicking my ass.
On the playground his karate really started to make a difference over time. Jumping higher to dodge the kick ball while running the bases, etc, etc.
We never really fought for real over the years, and remained good friends, until in the 8th grade when we both liked the same alpha cool girl, and he ended up as her boyfriend. But she and I maintained a too close friendship, which culminated with me feeling her boob at a party, with her temporary permission.
Well, my rival and friend found out about it, not by her, and he gave me a bit of a sucker punch in the arm, which had me near tears or even closer than near.
He went on to play college football as a strong safety, but not before punching a rival in the face so hard that he broke the kid's jaw and shredded his face skin. I'm lucky he treated me with more mercy back in 8th grade.
