Use your Own dirt

The Contest........

Two men talked among themselves and decided they did not need God anymore.
So they went up on a mountain and called God. He came down, and they told
Him: "We have decided that we no longer need You at all." God looked at
them and said: "I think you Do need me." The two men said: "Nope. We
don't, and to prove it we are going to have a man-making contest." God
said: "Okay, fine by me."

One of the men bent over and picked up a fistful of dirt, at which point
God stopped him and said: "Uh-uh. Use your Own dirt."
