A spaceship lands in St. Peter's square in Rome. An alien emerges and is immediately granted an audience with the Pope.

After the alien assures the Pope they come in peace, the Pope asks, "I know this question may sound odd, but I was wondering if your species know about Jesus Christ?"

"Of course we do!”, says the alien, “He visits our planet every couple of years! Fantastic guy!"

"Every two years?" gasps the Pope. "We're still waiting for his *second* coming!"
