Poster from Brad Kozak's post (linked above)
This poster, from one of my favorite short-lived series Firefly (sort of a live-action Cowboy Bebop), made U of Wisconsin-Stout officials go ballistic (Can I even use that word?) when a theatre professor posted it on his door.
Apparently he's posted things there for a long time, but this particular one set off the trip-wire of political correctness, which obviously trumps a 200+ year-old scrap of paper called the Constitution.
Please click on the link and give Mr. Kozak's post a look. There's another poster in there which did not further endear the professor to the powers that be at that institution.
This is a public service announcement from Paul_In_Houston.
Addendum - 30 Sep 2011 - Context: Captain Malcolm Reynolds (the dude in the poster) and his motley crew make a pretty much off-the-books living by using their "Firefly" class cargo ship to transport various and sundry items and passengers to other worlds. On learning that one of his passengers has smuggled aboard his sister (a greatly sought-after fugitive from the oppressive Alliance) and berating said passenger about them being an albatross he just doesn't really need at this point, the passenger openly wonders about being killed in his sleep, prompting Mal to clarify things a bit.
