bunny_hugger and I form a two-doctorate household, so it probably won't surprise you that we've both had thoughts of going back to school. I for one was a very good grad student, puttering along at a nice casual pace, picking up two or three classes a semester and even doing pretty near all the work as best I understood it and coming home to watch Cartoon Network and mess around on the Internet. It's a great lifestyle, if you can afford it, and grad school is the right place to afford it. But that's not exactly where either of us is anymore.
Still, I have had thoughts about going back to school, not really to burnish my CV or anything but because it's fun going to classes and studying and having homework and all that. At least if you're the right, academic-style temperament, and I am. She is, too. We mentioned this aloud last night and it lead to quite the discovery.
The university where bunny_hugger teaches has a very satisfying tuition-deferment plan for faculty and for family of faculty, by which they even include husbands (rather than children). And it extends to the non-tenure-track position which she holds, too. Either of us could go back to pick up a second Master's on her employer's dime and it wouldn't cost anything but the time and textbooks involved.
This could be particularly dangerous for me, since I have a hard time running across anything I don't find interesting enough to pursue more. I had formed rough ideas of thinking it'd be worth getting back to Physics (as it aligns so with my mathematical interests) or History (as so much of what I read for fun is that), although if I can get courses for the cost of just riding up twice a week and taking my turn in the carpool, well, it could be almost the Tenured Grad Student lifestyle all over again.
Trivia: Between 1921 and 1924 Rutgers's College of Agriculture saw undergraduate enrollment drop from 109 students to 80. Declines were common in agriculture schools across the United States but were generally not so severe. Graduate enrollment remained steady about about thirty students.

Currently Reading: Eve of Destruction: How 1965 Transformed America, James T Patterson. I like that the foreword mentions how many books pick out individual years for being The Year That Changed Everything, and Patterson even mentions two within the same decade posited by different authors as the Year When Everything Changed.
