In someone's home, what kind of art would give you pause or weird you out?

Bit by bit, I’m decorating my apartment with an odd assortment of things from a friend’s photography to autographed pictures of my favorite Star Trek actors to the odd thing I pick up from work.

Since I’ve been thinking about this a lot, I’m curious as to what kind of art would make my fellow Jellies go, “Huh, that’s strange,” or “Whoa, wasn’t expecting that,” or even ” What the hell? Who would put that in their house?”
