Well, I wasn't sure if this should go under Religion and Philosophy section rather than Jokes, but anyhow.
A priest, a minister, and a rabbi wanted to see who was best at their job, so each went into the woods to find a bear and try to convert it,
Later, they all got together. The priest begins: "When I found the bear, I read to him from the catcechism and sprinkled him with holy water. Next week is his first Communion."
The minister says: "I found a bear by the stream and preached God's Holy Word. The bear was so mesmerized that he let me baptize him."
They both look down at the rabbi, who is lying on a stretcher in a full body cast. "Looking back," he says, "maybe I should not have started with the circumcision."
