Depending on my mood, I'd do one of three things:

1.) Slap Him in His face, and show Him what the hell the world is like right now, time to get up off your cloudy bearded behind!

2.) Slap Him in His face, and take over, letting my misanthropy take over from there :P

3.) Slap Him in His face, and ask if he's trying to insult my intelligence; where are the Space Kitties?!

But since I don't really belive in a God or Heaven, it doesn't really matter. Meh.
