Another story I've had for a while that's taken on new meaning in light of recent scientific advances.

One day a group of scientists got together and decided that man had come a
long way and no longer needed God. So they picked one scientist to go and
tell Him that they were done with Him. The scientist walked up to God and
said, "God, we've decided that we no longer need you. We're to the point
that we can clone people and do many miraculous things, so why don't you just
go on and get lost."

God listened very patiently and kindly to the man and after the scientist was
done talking, God said, "Very well, how about this, let's say we have a man
making contest." to which the scientist replied, "OK, great!" but God added,
"Now, we're going to do this just like I did back in the old days with Adam."
the scientist said, "sure, no problem" and bent down and grabbed himself a
handful of dirt. God just looked at him and said, "No, no, no. You go make
your own dirt!"
