Well, I work in military construction. I would figure the Bizarro version would be military destruction, i.e. instead of building, I’d be bringing it down (rather quickly).

Here’s where it gets weird: I’m going to Explosive Ordnance School this August. 
Hahahaha my bizarro job would be actual work, since I’m currently on unemployment. On second thought, that sounds like my conception of the normal working world as a youngster: absolutely bizarro on a routine basis.
I guess I’d be an astrologer then… 
My job’s a lot easier, too, I encourage them to not practice the violin. Result!
Ha! I’m a psychiatrist, so in bizarro I won’t listen to a thing you say, then take pills from you so I can spend the rest of the day enjoyably hallucinating!
