What is my initial thought? Here comes the Lord and his band of Angels! Dangit! I knew I shouldn't have waited so long to turn my life over to him.
The first person I would contact? ummm... I'd log onto JoeUser.com and post an article about it... I would explore the ins and outs of the book of Revelation coming to pass, and hopefully start an intense discussion about the 'end times'
My last day on Earth? hmmm... the right thing to do would be to pray for my soul. Only i'm not very good at doing the right thing, so I'd prob'ly get naked and drunk, and run around the streets yelling something to the effect of "the sky is falling!" It would be nice to get laid one more time before dying, but since I can't seem to pull that off now, I don't know what makes me think the end of the world would be any different. Unless I lower my standards I guess... Let me get back to you on that one.
My last evening? Assuming that I don't get shot for my behavior from earlier in the day, I would prob'ly get around to doing that prayer thing... I think Jesus would prob'ly laugh at me though. Since he knows in my heart that I'm a little heathen.
Be doing when the final moment arrives? all bullshit aside, I'd like to be secure that my soul was going to Heaven. What i'm doing wouldn't really matter if that was the case.
