I have laughed at far worse things. A morbid, dark sense of humor happens to pretty much everyone in my job, but I came into it already enjoying the very offensive. Fortunately it doesn't clash with my coworkers much at all, because they're also horrible, warped people.

As far as family goes, my sister and I do not have much in common, but one thing we do share is our sense of humor. She's the only person I know outside of the internet who appreciates the orange head joke as much as I do. My parents don't share our humor, unfortunately.
