Well he thinks for a while and says let's put, "You are not getting older you are getting better."
The salesman asks "How do you want me to put it?"
The man says, "Well, put 'You are not getting older', at the top and 'You are getting better' at the bottom."

You are not getting older at the top
You are getting better at the bottom
