Heh heh heh. The fun you could have!

Find out who sits next to a printer that isn't yours, find out their name, and print:

"We're watching you, Mr. Such-and-such".

I would print out some gay porn so it grosses them out.

Combine this with the program that lets you change the text on the screen, and we're larfink!
