My old school (graduated now, so . . .) is a breeding ground for weird and chaotic stuff. One incident that my teacher was involved in was when a bunch of delinquents were making fun of him behind his back. He found out and confronted them. The talk between them only made things worse, and my teacher challenged him to a brawl in the bathroom after school. My teacher won, and afterwards they became friends and the delinquent became the godfather of his kid. 

Another incident that was more on the weird side: Someone had the bright idea to fill our water dispensers with cockroach corpses.
