A teacher, a doctor, and a Politician all die and end up at the Pearly Gates.
St. Peter meets them there and says "It's good to have you here, but we're a little over crowded today. You'll each have to answer 1 question before I can let you in."
Peter turns to the teacher and says "What was the name of the famous ship that hit an iceberg and sank in the early 1900s?" The teacher smiles and says "That's easy. The Titanic."
Then he turns to the doctor and says "How many people died on the Titanic?" The doctor says "Well, that's a tricky one, but luckily I just saw the film, so I know. 1500."
Peter lets the doctor in, too.
Then Peter turns to the Politician and says "Name them!"
