I'll be the first to say it in all seriousness...I think this guy is dangerous. You, and your co-workers should not be subjected to this kind of behavior in the workplace. You can make light of this all you want, and continue to patronize his erratic moods, but it is downright unsafe to not deal with this directly. Talk with his manager first. Is there a history of this? Explain the uncomfortable atmosphere that this behavior creates. HR should step in quickly. They recognize these things easier than the rest of the associates, and know how to deal with it. I had a guy working for me who had lost perspective and was unhappy. I worried about what he might do, and counseled him out. I am willing to bet everyone is happier as a result. All the experienced managers will tell you, the most dangerous thing you can do in this circumstance is ignore it.
