One of God's helpers

During a college class a professor, professing that he was an atheist to the class that he was teaching told them that he was going to prove to them that there is no God.
He said, "God, if you are real, I want you to knock me off of this platform. I'll give you 15 minutes!"
Ten minutes went by. He kept taunting God, saying, "Here I am God. I'm waiting!"
It got down to the last couple of minutes and a young veteran service member just released from being on active duty and newly registered in the class walked up to the professor, and hit him full force in the face, which sent him tumbling from his platform.
The professor struggled up, obviously shaken and yelled, "What's the matter with you? Why did you do that?"
The veteran replied, "God was busy; so he sent me!"
