Received via e-mail from a former co-worker:
The priest was presenting a children's sermon and asked the children if they knew what the Resurrection was.
Now, asking questions during children's sermons is crucial, but at the same time, asking children questions in front of a congregation can also be very dangerous. In response to the question, a little boy raised his hand.
The priest called on him and the boy said, "I know that if you have a resurrection that lasts more than four hours you are supposed to call the doctor."
It took ten minutes for the congregation to settle down enough for the service to continue.
