A new arrival in Heaven (much to his surprise, actually, but that's another story) was being given the usual newcomer's tour of Heaven by the Angel Fred. In the course of the tour, they passed a beautiful mansion (as reported, God's Heaven has many mansions—Catholics, Protestants of various flavors, Muslims, Buddhists, Taoists, Hindus, Rastafarians, and, yes, agnostics and atheists—MANY mansions), but unlike the others he'd just seen, this one had a high wall around it.

The new arrival tapped Fred on the right wing and asked, "Why does that mansion have a high wall around it?"

"Oh, THAT one," the Angel Fred responded, "Those are the [fill in denomination of your choice]. They think they're the only ones here, and if they knew there were others here besides them, as far as they're concerned, it wouldn't be heaven."
