No, I'm a student. I can get in trouble for that kind of stuff :)
What?
When I was a student, and when I was supervising students, practical
jokes were _expected_. There were rules, like no permanent damage (to
physical items or data (like computer files)). Nothing against the law.
Nothing _too_ dangerous.
And yes, I've been caught by practical jokes. And yes, I laughed
afterwards - and then played a joke in return.
When I was in high school (we had an HP 3000), if you could hack MPE
and "steal" operator or supervisor privileges then, provided that you
didn't do anything terrible with them, you could keep them. And you
often got recruited for temp operator duty. Ah... those were the
days... when every machine on the ARPANET had a guest account...
