Been very lucky [?] in that most of my "real" jobs have been, at least, fairly interesting.
Back when I was a student, and quite in need of additional funds - stop sniggering, the books on my course were f'ing expensive, even second hand, and one tutor kept specifying the "new edition" [written by his best mate, natch].
I ended up stuffing envelopes for mail shots and some door-to-door freesheet deliveries.
For the first job, on the second day our "supervisor" buggered off for a meeting or something after handing out a bollocking for not reaching the target te day before. As soon as he'd gone, we had a think and totally re-arranged our work stream into a production line. We ran out of materials mid-afternoon, just as he came back & started to explode that we'd interfered with the process ... his boss came in and made him leave the room. We didn't see him for the rest of the week. But we got the best part of a fortnights work done in four days - and a hefty bonus as a result. Next short vacation, and we were on the job again, and made a similar killing.
I lasted about half-way around the route for the freesheet, after a contretemps with a nasty bloke and his rancid dogs ...
