Most people in this thread are being super serious, but my first thought was 'standup comedian'. ^^;
I guess if you wanna be cute, you could say even actual standup comedians hate their job, but regardless of how much I could hate or enjoy it I really just lack any and all of the necessary skills. I'm not a quick thinker, I don't write standup-type humor very well, I can barely even emote with my voice. I'd just be a disaster...
Oooh, my first job last year was a little like that. There just wasn't enough work for all the new hires to do, especially not for me.
Only instead of being given fake busywork, this was just...not acknowledged. Like, I didn't get trained to do anything complex, I'd finish all the basic tasks I could do in the first two hours, and for the rest of the day I had to look busy or get scolded.
And honestly, even if I didn't get quietly laid off within 3 months (seriously, at some point they just stopped calling) I don't think I would have been satisfied filling bottles and sweeping floors and pretending I could fix the analyzer in the back...I went to school to become a scientist, not a glorified janitor. ;/
