The sailors that find him are surprised to see three large buildings on the island.
They ask the man why he built the buildings.
“This first building is my house,” he says
“I was able to set up a crude aqueduct to create some form of indoor plumbing”.
The sailors are impressed and ask about the second building.
“This second building is my church,” he says “I am a Christian and my faith is very important to me”.
The sailors nod in understanding and ask about the third building.
“Oh, that one,” the man says.
“That's the church I USED to go to”.
