Professional golfer Chi-Chi Rodriguez told many one-liners on the golf tour. At the U.S. Open in 1979, Rodriguez joked about a pencil:
   
“That’s the best wood in the bag for an amateur. If you know how to use the pencil, you can score whatever you want to.”
 
Rodriguez told the joke several times. The one-liner has been printed in many golf books, usually shortened to: “The best wood in an amateur’s bag is a pencil.”
