Definitely did 6. a good amount of times.

The best we got up to was the year we found the admin password for the default image root user in some cached Skype logs. First we would SSH into random people's systems and use Applescript to type random things etc., bonus points if they currently were presenting something. We got bored of that pretty quick and resorted to just selling the ability to do stuff as an admin like installing things.

Earlier in middle school we figured out that the MacBooks the school issued had an IR receiver and the apple remote available at the time could trigger some Fullscreen tools by hitting a button on the remote and aiming at a victims computer, again mostly to disrupt teacher presentations.

Both bits of fun came to an end when some kid figured it out and ratted us out. When they figured out I was selling root access (installed CoD4 for a friend's little brother and changed the root password for them at extra cost, when they couldn't remember what they changed it to the went to the admin) all hell broke loose and they confiscated the laptops to re-image... no fun.
