I will relate this little tale, just to wet your insatiable appetites for senseless violence. Once when I was about 15, one of the neighborhood bullies, who fought in Golden Gloves and even won before and was taller than me and almost twice my weight, started a fight with me and a couple of friends. He was trying to control the neighbor hood pool and tennis courts and who could use it, like he always did, which happened to be next to his parents townhouse.
Well, he came out with a baseball bat and started swinging it at us, and he made the sorry mistake of hitting me on the leg. I started screaming at him, and he sent me into an uncontrolled rage, and I reached over and grabbed a 6 foot fence picket off the fence that was somewhat loose and knocked him over the head with it, and started pummeling him with it until it broke, and he dropped the bat and he went running inside to get his dad, who was a lot larger than he was.
When his dad first came out, he was pretty mad until he saw we were all half as big as his son was. He then turned on his whiney son, still holding his head where I hit him, and then hit him on the back of the head and asked him WTH he was doing attacking us, and why wasn't he able to take care of himself against us in the first place. He grabbed him by the arm, and made him apologize to us.
After that, we became good friends for years until we finally sold the townhouse and moved away.
And I found out later that one of my ancestors was a carnival attraction who used to be the strong man who would fight anyone who challenged him for a fight, for cash, and he never lost a fight. And my grandpa was also a boxer for many years who won a lot of his fights with a knockout. So the next time you challenege that scrawny guy at a bar just for kicks, just remember he may be able to defend himself and knock you out for your stupidity. Because for some people, fighting and self defense is just in their genes.
