Back in the old days, ie. before facebook, I used to save all my funny email attachments to a folder. I got talking to one of the support guys. Seemed a nice fella. So, I network shared my folder and told him to how to connect. I did suggest that he probably shouldn't share it with everyone else in support as some of the material was a tad risqué.

I realised he hadn't taken notice of this advice when I walked in the office and all the support PC CD drives were randomly opening and closing and the PCs playing farting noises. (Anyone remember that?)

I had to go round all the PCs and kill the process.

I then returned to my own machine and disconnected the shared drive.
