I made them up.

Work at a post office and swap people's addresses by filling out those change of address forms.

Work as a mailman and steal any magazines that go to your route.

Become a cop, drink massive amounts of water, and take pisses in those water jug type water fountains. If your piss is clear, no one will know...

Get a job as a teacher and "accidentally" set the school on fire.

Get a job as a janitor at a school and destroy teachers' records of students that are really good or really bad. Or, for the really daring, swap the names of the students so the good kids get bad grades and bad kids get good grades.
