Pretty realistic for Mike Rowe supposedly. Dude hit burnout a long time ago.
Supposedly the gross episodes like septic tanks and sewer work are what he looks forward to because everything else is just a life of orientation in every career field with all the paperwork and boring supervisor introductions that it entails.
Hell, he’d be disappointed by the lack of death and feces.
I recall him saying castrating horses was boring because of all the setup and dull mechanical process, but helping them deliver foals was fun since it was tense and unexpected. That was early on in the show too.
