Ok, another joke, this time with an atheist theme:
An atheist was hiking through the forest when suddenly he came upon the biggest grizzly bear he had ever seen.
He panicked and started running, with the grizzly bear hot on his heels.
Before he knew what he was doing, he started to pray. "Dear God," he said, "You know I have been an atheist my whole life and I think it might be a little late to change me into a religious man. But can you do me a favor and persuade this giant, hungry bear to act like a Christian?"
Instantly the forest filled with light and the bear stopped his chase. The man breathed a sigh of relief.
Then the bear fell down on his knees, clasped his front paws, and said "Dear Lord, for this meal which I am about to receive, make me truly thankful."
