St. Peter is very busy in heaven, so he leaves a sign by the pearly gates: "For service, ring bell." He's barely gone when the bell rings. He rushes back to the gates, but no one's there. St. Peter goes back to work, but the bell rings again. He rushes back to the gates, and again no one's there. Growing annoyed, he returns to work. Ding! The bell rings a third time. St. Peter goes back to the gates, but still no one's there. "OK, that's it," he mutters. "What's going on?" He hides a short distance away, and a moment later, a little old man walks up and rings the bell. St. Peter jumps out and yells, "Are you the guy who keeps ringing the bell?" "Yes," the old many says. "Well, why?" "They keep resuscitating me."
