About ten years ago...
...I was working as the junior member of a 2 man IT department for a college. Students would rock up all the time with "My internet isn't working! Help!" which nearly always meant that we'd detected something horrible coming off the network port in their room and blocked them at the switch until they brought the offending machine in for decontamination.
This one girl brought in her pc with a DVD in the drive. Nothing terribly surprising about that, but this machine was in a real state and we had to resort to a live CD to get it booted, I didn't think about the DVD, I just put it on my desk until the computer was clean. When she came to get it back, I thought I ought to put the disc back in. She had her machine set to auto play DVDs. I saw the look on her face go from "Oh, thankyou, wouldn't want to leave that behind" to "Actually, what IS that?" to "Oh god NO!" just as it started playing a shaky camcorder quality porn film staring her, some other girl, and about 10 obviously incredibly drunk guys.
All you can really do at that point is close the lid and tell them to just take it away. No, really, I don't want to know. Don't say anything, just take your machine and go and we'll forget this ever happened.
