The Classic 

A babysitter is staying over at a client’s house when she gets a phone call. “I’m going to kill you,” a strange voice on the other end of the line says. She tries to ignore it, but she gets another phone call. “I’m going to kill you,” the voice tells her again. She calls the police and tells them about the threatening calls. The police officer promises to run a trace to find out where the strange phone calls are coming from. 

“Oh my god!” the officer says, suddenly. “The calls are coming from inside the house! Get out! Get out now!” 

But there was no reply… 

Okay, so there’s a flood. A man is caught in it, and he climbs up onto the roof of his house in order to escape the water. As he’s sitting there, another man comes by in a raft.

“Jump in!” the man says. “We can row to safety!”

The man on the roof says, “No, leave me. I have faith that God will save me.”

So the man in the raft paddles away.
