When I was younger I liked to ponder the world, and those things that are incomprehensible to mankind (or, at least, me). I thought the following quote summed it up perfectly at the time:
If God is omnipotent, can he make a rock so heavy that he cannot lift it?

With the limitations that language offer us, and the restrictions of my feeble mind, I STILL have not come up with the answer to that.
