The traveling salesman was passing through a small western town selling an elixir which he declared: “will make men live to a great age!”
“Look at me,” he shouted. “Hale and hearty, I’m over 300 years old.”
“Is he really as old as that?” a bystander ask the youthful assistant.
“I can’t say,” replied the assistant. “I’ve only worked for him for just over a 100 years.”
