A petty thief, a teacher and a lawyer die in a plane crash and go up to Heaven's gates together.
When they get there they are stopped by St. Peter, who says: "Sorry, it's crowded up here, you need to answer a question correctly, or else you can't get in."
He looks at the teacher, and asks her: "What was the name of the famous ocean-liner that sank after hitting an iceberg?"
"Oh, that's easy," the teacher replies, "the Titanic."
So St. Peter lets her into Heaven.
Next he turns to the petty thief.
"How many people died on that ship?" St. Peter asks.
"Oooh, that's tough, but I saw the movie, and I think it was 1,500."
St. Peter steps away and the thief walks into Heaven.
Finally, St. Peter turns to the lawyer and says: "Name them."
