One of the courses had a professor who was an avowed atheist and a member of the ACLU.  One day the professor shocked the class when he came in. He looked to the ceiling and flatly stated, “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. You could hear a pin drop. Ten minutes went by and the professor proclaimed, “Here I am God. I’m still waiting.”

It got down to the last couple of minutes when the Marine got out of his chair,went up to the professor, and cold-cocked him knocking him off the platform.

The professor was out cold. The Marine went back to his seat and sat there, silently. The other students were shocked and stunned and sat there looking on in silence.

The professor eventually came to, noticeably shaken, looked at the Marine and asked, “What the hell is the matter with you? Why did you do that?”
