My sophomore or junior year of HS, saw a guy get tripped during an xc race. He quickly got back up, caught the dude who tripped him, and threw him into a chain link fence.
My senior year at sections, my friend was already having a shitty race, and some dude kept bumping into him from behind. He finally got so mad that he turned around and pushed him over, and kicked him into a ditch. We spent the entire off season, and all of track season thinking the guy totally hated my friend. So at the end of track season I'm taking to him and our league championship meet, and I ask him "so what's your side of the story from when *insert friends name* pushed you into a ditch at sections?" He responds with "That was *friend*?!". Appartebtly the dude and his teammate had already determined that it was an entirely different person from another school, and had come up with an elaborate plan to jump him at the final race of track season. When the found out it was my teammate everybody just laughed it off.
I had another buddy on the team, and he was kind of friends with this black kid on the team. The black kid had a bit of a learning disability, he wasn't retarded or anything, he was just a little slow. Anyway, at the same race, strangely enough, we were all hanging out waiting for shit to get started. We were doing the usual high school thing, dicking around, making fun of eachother. Then the insult of all insults came out, the most obnoxious kid in the league starts making fun of people for being virgins. Eventually someone makes fun of the black kid for it, and he just looks over at my buddy, because they were always messing with eachother, and he just goes "nah man, *friends name* is the only virgin here". And my friend just looks at him for a second, tilts his head and goes "Yeah. Well at least I'm not a f*cking n*gger." And everybody from all the other teams just lost their damn minds. My friend and the black kid start walking towards eachother, people are yelling, because for sure these two idiots are about to throw down right then and there. When they finally got to eachother they just gave eachother a bro hug and a slap on the back and walked away from eachother, leaving a group of hysterically laughing high schoolers in their wake. So that's not really a fight story, but pretty much everyone there thought it was gonna turn into one.
