Did you guys all go to high school with Sylvester Stallone, that all these arm wrestling competitions were just randomly breaking out?!?!?! When you guys won, did you not only win the respect of the bully, but also the respect of your estranged son in the process?
Well, I'm slightly heavier than the average male, I'm a pretty built 190, and I know the basics pretty well. So I'm not too concerned in a one of one fight with the average guy. But really, any average size dude who is halfway competent at a fighting art can beat up 90+ of the general population, so it's not really that big of a deal. Most people are out of shape, and have no idea how to fight.
..and no need to know how to fight. Plus in USland, don't they just shoot you? (they're always saying here that they would)
