Catchy Names

When I was introduced to a couple visiting our
congregation, I decided to remember their names
by noting they were the same as those of two
characters in a popular children's  
story.  

After the services I stopped to talk to them, and
as they were saying goodbye I teased, "Be careful
going up that hill! But you must get that all the time."  

They smiled politely but said nothing. After they left,
my wife asked, "What was that all about?"  

"Jack and Jill. Up the hill. Remember?" I said.  

"Yes, but what does that have to do with," she
pointed to the couple, "Dick and Jane?"
