crazy guy on the bus

There were three crazy guys on the bus with us yesterday but one was exceptional. When we got on the bus he was already talking out loud (to nobody?). He seemed intent on telling us the world is going to end with a tinge of "praise Jesus and pass the ammunition". I'll try to give a feeling for it:

The world is going to end.
Oil and gas.
The world is going to end.
Jesus is coming back soon.
The world is going to end.
I'm looking for Jesus.
See the signs; the world is going to end!
Why not start world war three? Might as well.
The world is going to end.
You probably think I need a doctor; I've already seen the doctors.
The world is going to end.

He went on and on like that for a while. He got off the bus where we did and once he got off he was looking at the sky and talked about looking for Jesus. I asked Sarah about it shortly after we passed him, "When did his world end?"
