I didn't see this post of Ink's till a bit late to comment. But I loved the question and the answers. In many ways, my dream job is the one I have, tarted up a bit (as many of the other people who commented seem to have felt). I like the idea of teaching Latin to enthusiastic students and spending summers in the Mediterranean; being a curator of medieval manuscripts would be great; or maybe I could be the engineer who invents Belle's "poof" machine for idiots.
And finally, I would love to be in charge of caring for big cats at a really good zoo.
