Joke: Christians in heaven

A man dies and goes to Heaven. The angel Gabriel meets him at the
Pearly Gates and takes him on a guided tour.

The man sees various groups of people all standing around and talking
to each other.

"These are the Buddhists," says Gabriel. "And over there are the
Jews, and the Hindus. Over here are the Muslims, and over yonder are
the Jehova's Witnesses." In fact, the man sees every religious group,
every nationality, and every culture in Heaven.

Eventually, the pair comes to a large wall. "Hey, what's this wall
doing in Heaven?" asked the man.

"Shhhh!" said Gabriel. "Lower your voice. Behind that wall are the
Christians. They like to think that they're the only ones here."
