A known atheist,

A College Professor, who was a known atheist, stood on his chair and said, "If GOD really exists, knock me off my chair."

Nothing happened.

The class was quiet so he said "See? I'll give it a couple more minutes".

An ARMY Vet stood up, punched him in the face knocking him out and off the chair, then sat back down.

As the Professor came to he looked at the Vet  and said, "WHY'D YOU DO THAT?"

The Vet stood and stated  "GOD was busy protecting my buddies still fighting for your right to say and do stupid shit like this, so HE ASKED ME to knock you off the chair"
