A Sign From Above
 

An atheist professor was teaching a college class when he told the class that he was going to prove that there is no God. He said, "God, if you are real, then I dare You to knock me off this platform. I'll give you 15 minutes!" Ten minutes went by. He kept taunting God, saying, "Here I am, God. I'm still waiting." The young college students didn’t know what to think but were afraid to challenge the professor openly in his classroom. He got down to the last couple of minutes when a young Special Forces NCO, just released after a year of combat duty in Iraq and newly enrolled in the university, walked up to the professor, hit him full force in the face, and sent him flying from his platform.

The professor struggled up, obviously shaken, and yelled, "What's the matter with you? Why did you do that?"
The young NCO coolly replied, "God's a little busy watching over my buddies in Iraq right now, Professor, so He sent me to deliver His reply to your challenge."
