God is worn out, so he tells St. Peter, "You know, I need a vacation. Got any suggestions about where I might go?" St. Peter thinks, and then says, "How about Jupiter? It's nice this time of year." God says, "No, too much gravity on Jupiter, it hurts my back." St. Peter says, "OK... Hmmm. How about Mercury?" God says, "No way! It's way too hot on Mercury for me." St. Peter exclaims, "I've got it! How about going to earth for your vacation?" God says, "Are you kidding? I went there 2,000 years ago, and had an affair with some Jewish girl, and they're still talking about it!"
