How did you deal with a bully in school?

I remember some guy trying to pick on me when I had a broken arm. He pushed past me and said "out of the way cripple". I turned and hit him a massive sweeping kick to the left leg. He tripped and landed flat on his face.

He got up and hurried away. Which surprised me. It's not like I was gonna win a fight with one arm 😂 and he was bigger than me.
