Many of these over the years..
A few that stand out:
Doing a remote session to help someone with a web-based app and midway through, noticing the several other Chrome tabs he had open were all going to gay porn sites. I discreetly helped him and did not utter a word. It was after hours and he was at home, so have at it was my philosophy. Just don't infect your machine with something.
A colleague of mine trying to track down who was spending hours on the company LAN visiting porn sites. As fast as she would block sites, he would find more. This was back in the days before out of the box proxies and web filters, and coming from another tech field, her skills managing a corporate LAN may not have been as up to snuff as they could be, at first. She eventually tracked down the offending machine. Of course it was our CEO's. Not sure how she handled that awkward talk..
Visiting an engineer's desk to assist him with something and finding his desktop wallpaper consisted of a woman spread-eagled in a fashion that would make a Penthouse editor or gynecologist blush. He was eventually fired, though not for that, and his laptop was turned over to police for investigation of child porn.
