Marine vs College prof

    An atheist professor was teaching a college class and he told the class that he was going to prove that there is no 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 Marine just returned from Afghanistan and released from active duty and newly registered in the class 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 Marine replied, "God was real busy watching over the ones protecting your freedom so he sent me.". That Marines name was Albert Einstein.

You forgot to include the part about how the Marine got expelled, lost his wife and kids, and died homeless. While the professor lived a very happy and long life.

Also, I don't think his name was Albert Einstein, I think you are mistaken.
