Man dies and goes to heaven, filled with rooms he hears a party behind each door is happening. St. Peter (or whoever the afterlife tour guide is) took him to the first door and opened it. The room was full of Muslims welcoming the man to come in and join them. Passing they moved on to the next door to find a room full of Jewish people celebrating the afterlife. Next a room of Buddhists - all calling for the man to come in and join the splendor of the afterlife. The next room, however, is passed by as St Peter whispers, "shhhh just skip that one. It's the Christians, they think they're the only ones here."
