I did a search for theology jokes a while back and I found this:
Karl Barth, Rudolf Bultmann and Paul Tillich are taking a break together, fishing on Lake Geneva. They are having a lovely time, smoking their pipes, chatting idly.
It’s hot and they are getting thirsty. So Karl Barth gets up, steps out of the boat, and walks across the water to the shore, gets some beers and returns.
It’s quite hot so the beer doesn’t last long. Barth tells Tillich: “your turn, Paul”. Tillich gets up, steps outside the boat, walks across the water, and fetches some beer.
It is getting really hot now, and the beer is finished once again. Bultmann is beginning to sweat particularly profusely… and finally Barth asks him too: “Come on, Rudolf, your turn now.” With a slight tremor in his knees, Bultmann gets up, steps out of the boat, and sinks like a stone. Fortunately he is a good swimmer; he drags himself back into the boat and sulks at the far end.
Tillich turns to Barth and says: “Do you think we should have told him where the stepping stones are?”
Barth looks at him in astonishment and replies: “What stones?”

One day the Pope received a phone call from an archaeologist in Palestine. “Holy Father,” the voice said, “I don’t quite know how to tell you this, but we have discovered what proves beyond doubt to be the very bones of Jesus!” Hanging up, the Pope convened his closest advisors. Explaining the situation, he asked the stunned clerics for suggestions. One stammered, “Holy Father, I believe there is a Protestant theologian in America who might be able to help us. His name is Paul Tillich.” Wasting no time, the Pope called Tillich’s office in New York. “Herr Tillich, I’m afraid we have quite a problem here, and we hope perhaps you can advise us. Archaeologists in the Holy Land have discovered the bones of our Lord Jesus!” Silent seconds passed, finally broken by Tillich’s heavy German accent: “Ach… he lived?”
