Daniel Meets A Crazy Person

So I was leaving my apartment to go pick up a pizza. There was a man out there wandering in the parking lot, I can see him from my doorstep looking down the stairwell, and he looks up at me. For a moment I didn't move, then finally headed down to my car, as he started backing away from me.

First of all he said something to me about needing carbon copies or something, not really sure. Something about needing more than one carbon copy or something. I said "okay" to him and continued to my car, as he turned to walk out of the parking lot. But before i could get in my car, he turned back to me and started again, this time going into a long preaching tirade of a word salad, with something about centrifuges (and putting the Pearl of Great Price in a centrifuge?), something about him having pride in his work, and at one point quoting the song Message in a Bottle by Sting. He went on for a couple minutes before finally stopping, and when he was done all I could say was "okay" again. 

As I pulled out of the parking lot, I saw he had stopped and engaged with someone else from my building who had gone out to smoke, and the expression on her face matched what I felt about the guy as well. He was gone when I got back with the pizza.
