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

When I worked in data entry fresh our of college, there was a mass firing. Turns out people were signing in and leaving. Like, to go to the movies, to the store, to just hang out, for their entire shift, and would then log out at the end of the day. Damn near every person under 30 was gone. Some quit before they could get fired. It took all day, and there were plenty of performances. Now, it was data entry, which meant our activity was tracked, from the inactivity to how much we got through in a day. I have no idea how they didn't think anyone would notice.
