back at client logic, a freind and I would run a program in the back ground on other peoples PC’s letting us maximize/minimize windows, open a website of our choosing, open the cd tray, make our own error messages…
like " have you have homosexual encounters" with only a “yes” button…

and we would play quake the entire time.
IT actually put a file on the C; drive called: if quake gets installed on this pc again your name will be reported to human resources.

after that we never logged in as ourselfs again.
