A fellow had been stranded on a desert island for 20 years. Finally, he saw a modern cruise ship which had anchored unusually close to shore in order to permit a little snorkeling. Catching someone's attention, the man was taken on board. After getting himself cleaned up and dressed, he was invited to the captain's table for dinner.

"So," asked the captain, "how did you manage to survive by yourself all those years?"

The castaway pointed at the porthole and said: "By the grace of God. You see those three huts out there on the beach?'

"I see them," said the captain. "You must spend a lot of time in them."

"That's right," said the beach bum. "In the middle hut I live, cook my fish and sleep in a hammock that I made for myself. The hut on the right is where I go to church. Never miss a Sunday. I celebrate Christmas and Easter, give myself communion once a month, and even hold a revival every other year. That's why I've been able to survive so long ... by attending church regularly."

"Amazing," said the captain. "So what about the hut on the left?"

"Oh, that's where I used to go to church."
