How many mystery writers does it take to change a light bulb?
Two. One to screw the bulb almost all the way in, and one to give a surprising twist at the end.
A ship, sailing past a remote island, spots a man who has been stranded there for several years. The Captain goes ashore to rescue him and the man insists on showing him around before they go back to the boat. The Captain is a bit puzzled as he notices that there are three huts, but he is all alone.
“What’s the first hut for?” he asks.
“That’s my house,” says the castaway.
“What’s the second hut for?”
“That’s my church.”
“And the third hut?”
“Oh, that?” sniffs the castaway. “That’s the church I used to go to.”
