What’s the craziest or most outrageous (maybe even NSFW) incident that led to someone being fired from your workplace?

It's health care so obviously we were told that we'd have to be vaccinated against COVID or be fired, like many. Most people went along with it, but the CEO sent out a final warning email to the whole network, and this antivax dingdong somehow managed to reply all to the CEO giving him a patronizing lecture about how COVID wasn't real, how nobody had died of it, and how he had read several patient charts that proved this, and how the CEO was making a very big mistake, and how he, this clerk, knew science better than the CEO did. He was fired for reading patient charts he didn't belong in, of course. The email was super patronizing and he claimed to have an M.Sc and that meant he knew better, despite the fact he was working as a clerk, and gave all sorts of false "evidence".

Anyway he was fired and reply all to the CEO is disabled.
