Out of curiosity, I just did a few searches of the username of one of my annoying cubicle neighbors (first initial plus last name).

I found a site where he has made a ton of posts.  From his profile pic, I know it is him.  The people on that board engage in plenty of what I would call "sewer talk".  This guy has made plenty of racist, sexist, homophobic, and anti-obese comments.  He has used terms that I had never even heard of, such as "hood rat" and "sand n*gger".  I had to go to urbandictionary.com to find out what they mean.

And in the ultimate irony, I saw a post where he complained about another co-worker who is from another country and hasn't yet learned American customs.  ROTFL!!!

I better not go into too many details...  based on the topic of that message board, he has what I would consider "dangerous" hobbies.  I actually am a little scared of him now.
