Me? God? A day? I'd light this planet and make the sun look like a firecracker by comparison. We deserve no less. If you still want humanity around, then I'd get rid of natural suffering- you know, hurricanes, tornadoes, tsunamis, volcanoes, earthquakes, etc. Instead, I figure my all-powerful and all-knowing wise-ass might find some way to accomplish the same without causing tragedy.

I'd certainly torment the local political leaders, that's for sure...

I dunno... I might also just be feeling rather lazy at the moment. I might just make a large flat-screen TV pop in so I can look at other people's misfortunes.

Right after making sure I have a place to stay in the US, Canada, or United Kingdom. This calls for priorities, of course!
