St Peter is standing at heaven's gate when a man walks up."Welcome to heaven my son. What did you do with your life?""I was a policeman," he responded."What kind of policeman?" St Peter asked."I was a vice officer. I kept dangerous narcotics out of the hands of kids.""Wonderful my son, welcome to heaven. Pass through the gates."A few moments later a second man walks up."Welcome to heaven my son. What did you do with your life?""I was a policeman," he responded."What kind of policeman?" St Peter asked."I was a traffic officer. I kept the roads and highways safe for travelers.""Well done. Pass through the gates into paradise."A few moments later a third man walks up."Welcome to heaven my son. What did you do with your life?""I was a policeman," he responded."What kind of policeman?" St Peter asked."I was a Military Policeman, Sir."
