If Michael Myers (Halloween) was looking for a job, what would be the most/least suitable vacancy for which he could apply?

Now of course this is a purely fictional scenario, for as those of you who know/care, he was in fact, as mad as a box of frogs.
What if though, what if he had a “normal” well adjusted childhood?
What if he grew up to be a well respected member of the community, a good egg?
A career oppurtunity that would have suited him well, and/or one which would have been just asking for trouble?
