Yes, I had a similar experience in high school. I ended up modifying a virus that infected a bunch of computers and causing problems, so I got kicked out the lab until the next year (but this was late September, so no biggie.)
The next year I mentioned to the teacher that I had something I wanted to play with, can I please get access to a PC (the lab computers were Acorns), and so he gave me after school access to the accounting classroom, more storage on the network drive (50MB when everyone else had 5!), and basically free reign if I didn't break things. So I didn't, and was running Tierra on piles of machines overnight, just to see it doing cool things, and getting in in the morning to save everything and reboot them. It certainly set me up well for the future.
And didn't break things, because I didn't want to kill the golden goose!
