An atheist professor was teaching a college class and he told the class that he was going to prove that there was not a God.
He said, "God if you are real, then I want 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"
He got down to the last couple of minutes and a huge 250-pound rugby player happened to walk by the door and heard what the professor said.
The rugby player walked into the classroom and in the last minute, he walked up, hit the professor full force, and sent him flying off the platform.
The professor got up, obviously shaken and said, "Where did you come from, and why did you do that?"
The football player replied, "God was busy; He sent me!"
