Until a few years ago, students were permitted to sleep overnight on the ubiquitous couches in the university student center of my Alma Mater. There are tales of a student who eschewed paying for housing and simply slept on the couches of the student center, and used locker room showers, for an entire year.
Unfortunately this individual's munchkinism led to the policy being revised to prevent this behavior - or so the tale goes.
When I was a grad student, I preferred to spend time in my office and go home only to shower once every two or three days (especially before TAing a class, when I would also put on shoes).
