Depends on how much I liked the job and if there was any hope of being paid what I'm paying now.

I can think of three jobs I would happily go back to if they paid what I get paid now (and the companies still existed). One game dev company, one game publisher, and one retail job, where I mostly chatted with other employees, stocked and cleaned up shelves, and helped about a 1-2 dozen customers a night.

My current job I might be willing to come back to at some point if I left it. It has some warts, but it's been pretty good overall.

Other past jobs, not unless they paid 50-100% more than I'm making now. Nothing against them necessarily, but I wouldn't want to have that job again.
