Perhaps I should add that I sort of interpreted maladjusted as “crazy,” which doesn’t necessarily mean rude, mean, sociopathic, etc. In addition to those things, I was also considering personal quirks, depression, self-esteem issues, egomania, and a host of other things. There’s a lot of nice crazy people out there.

I’d have to second this. I work in political operations now, and it seems to me that most politicians, whether their intentions are good to begin with or not, usually end up with such a completely convoluted view of reality that they should never be released back into the wild. I think we need a special reservation for former politicians.
We send ours overseas to be diplomats and consuls. Gets 'em off our hands, and they can embarrass themselves all they like over there.
Automobile salespersons, either new cars or used cars. This group of people putting the screws to the public.
UK School Inspectors.
They freak me out - and i’m a professional geek!
Advertisers.
People who spend their time trying to think of ways to make people feel bad/unnatractive/dirty/uncool/less worthy if they don’t use Product X.
Everyone that works in the animal hospital where I work tends to be a bit crazy. We all prefer animals to people and hate dealing with children. If only it weren’t frowned upon to lock the kids in kennels.
Motorcycle mechanics, without a doubt.
In four years as a bike wrench, I worked with:[ul][li]an apocalyptic speed freak,[/li][li]a con artist,[/li][li]a bunch of rednecks who thought traffic tickets were how you kept score and proof of insurance was something you forged,[/li][li]a boss who yelled at the customers and effectively quit his job before the end of the week, leaving the rest of us to run the shop on Saturday,[/ul]and I knew:[ul]a greaseball (and proud of it) who dug holes in the wall between the men’s and women’s bathrooms,[/li][li]an otherwise normal guy who talked mostly in rock lyrics and talked only in lyrics for a year (just to prove the point.)[/ul]These guys worked on Jap bikes. Trust me, the Harley dogs were the normal guys.[/li]
Admittedly, this years ago, but I only knew one well-adjusted motorcycle mechanic, and he quit to work on cars shortly before we actually met.
To narrow it down a bit further - Catalogers. These freaks make accountants seem like Oakland Raider fans by comparison.
Seriously messed up people.
Once again, the jobs that I’ve done seem to be popping up a lot.
Cab driver. Maybe it was just me, but the hours of semi-isolation always left me kind of loopy at the end of the night.
I enjoyed it, but being a cataloguer was more fun.
Most people I know in law enforcement are very paranoid.
Flame me if you will, but pre-school teachers are just a little whacked in the head with the happy stick, if you know what I mean. T’ain’t natural.
I don’t know any, but I imagine that being a prison guard could seriously screw you up.
Yes, I too have known a few very screwy cops. I also used to register potential cops for police academy courses at the local community college. THEY were a particularly scary population.
Nobody’s mentioned Postal Workers yet?
AFAIK, not professions in America, but certainly somewhere:
Executioner
Torturer/Interrogator
Bartenders!!!
Restaurant workers.
Wait staff that love to " be on stage " for the customer. The kind of people who make pickled lark’s vomit sound appetizing. Servers who flirt with everyone, I’m not talking about polite conversation. I mean the kind of people who were teases when in school, and still are.
Bussers that will eat from someone elses retrieved plate.
Kitchen staff that defies classification. You’ve not seen wierd ,until you’ve seen grown men doing Ethel Merman impressions, including choreography.
That would be me in my early 20’s. I did a stint as a security guard but on the 4-midnight shift. After 7 most everybody was gone and I’d put my feet up and read or type letters to friends or free association gibberish.
Lamar Mundane, I hear you! I think I mentioned this in another thread once. Catalogers are the strangest of the strange. Weird little xenophobic geeks who enjoy the AACR2R as light, weekend reading 
And I should know, I was a cataloger once–but not one of those, honest!
Wal-Mart.
Nobody’s mentioned tech support yet? Well, I suppose most of us techs don’t notice, because the folks that are a little socially off are so glad to find something they CAN talk about, that they’re sparkling wits about it.
On the other hand, I think that’s all phone jobs. We certainly don’t tech computers where I work now, and the boss just this week had to announce “Will everyone PLEASE put some shoes on when the clients show up at work.”
What? Fuzzy house-slippers don’t count?
