If Man is made in God's own image, then God must know how to laugh.

My favorite, although not particularly a Jesus joke:

A man lay dying in the hospital, seemingly beyond hope. A heart specialist came to his room, and said, I may be able to help you.

No, the man said, I have faith that the Good Lord will save me.

Later on, a brain surgeon stopped by. Perhaps I can help you, he said.

No, the man said again, I have faith that the Good Lord will save me.

Another doctor came to offer help, and again the man refused, saying that the Good Lord would save him.

The man died.

He made it to Heaven, and sat at the Lord's feet. Lord, he said, I don't understand. I had great faith that you would save me, but you let me die anyway.

And the Lord said, What are you talking about? I sent you those three doctors!
