Is this the place for theological jokes? I'm not sure this is a joke but...I sort of like it:

Jesus went to visit some prisoners on death row. He approached one inmate and said, "I've come to die for your sins."

The prisoner said, "Then what am I supposed to die for?"

Jesus pulled a little notebook out of his pocket and said, "I'm not sure, but if you'll give me your name, I'll see that one of my disciples gets back to you on this."
