I've had bad jobs, but nothing that I didn't, at least in part, enjoy at the time.
Lowest paying job was shipping at the Body Glove warehouse, but I more than made up for it in goofying off time.
Dirtiest job was security at a men's homeless shelter.
That one didn't pay much either, but the food was free.
Most physically demanding job was building sandbag bunkers in the Former Yugolavia only to have our company OC decide once it was finished (naturally) that it was too far forward and needed to be moved.
Another bunker collapsed a three story building into a single story building, while I was sleeping on the ground floor. That was fun.
Of course, that one needed to be rebuilt too.
