This picture at the Jesus Creed blog reminded me of a joke I heard from a college roommate:
A man is stranded on a desert island for some time. When he is finally rescued, his rescuers tour the island and discover three small huts.
"This one is where I lived," the man replies when asked about the huts. "And that one is where I went to church."
"What about the third hut?" the rescuers ask.
"Oh," the man replies, shaking his head, "that's where I used to go to church."
