Heh. In my relative youth, I was pranking a fellow co-op student on our work term fairly regularly. One of my faves was that he was on an HP Unix workstation in the shared computer room, and the X display defaulted to allowing all connections from other hosts. I'd set my DISPLAY environment variable to his desktop, then use xv to open whatever gross / unflattering / whatever pictures I'd found on the net that day.
