A Marine was attending a college course between missions in Iraq and Afghanistan. The professor, an avowed atheist, shocked the class one day when he walked in, looked toward the ceiling, and said loudly, "God, if you are real, then I want you to knock me off this platform. I'll give you exactly 15 minutes."
The lecture room fell silent and the professor began his lecture. Ten minutes went by and the professor proclaimed, "Here I am God and still waiting."
It got down to the last minute when the Marine stood up, walked toward the professor and threw his best punch knocking him off the platform and out cold. The Marine went back to his seat and sat down.
The other students were shocked and stunned and sat there looking on in silence. The professor came to, noticeably shaken, looked at the Marine and asked, "What is the matter with you? Why did you do that?"
The Marine calmly replied, "God is busy today protecting America's soldiers who are protecting your right to behave like an idiot and say stupid stuff. So, He sent me."
