I’m a no-nonsense kind of guy, so I really have a hard time thinking of things in the kind of jargon where someone calls themselves a “sanitation engineer” instead of a garbage man. You know, a lot of fancy words which when strung together sound important, but don’t really mean anything. I’m looking for a title like that for what someone in covert ops would refer to as “The Cleaner.” The kind of guy you call on when the shit’s hit the fan so hard that it’s jammed the blades. It doesn’t matter what went wrong, or what you should have done, this guy is the guy who can come in and save everybody’s bacon. Any ideas?

Nah, if I was going to do something like that it’d be Pete Puma Clubber Like A Harp Seal!

That was one of James Bond’s “cover” job titles in the 007 novels.
And what he did, definitely fits the bill. 
Happiness Restoration Consultant. For such an intense, bad-ass job, only a weirdly perky title will do!
