A man died and was giving a tour of the afterlife. To his surprise, there were people of all faiths represented, each in their own separate area. Finally they came to a wall that was so high, he couldn't see the top of it. "Who's in there?" His guide said, "Oh, that's the [insert denomination here]. They think they're the only ones up here".
