One Trick Pony, is a song and a movie by Paul Simon, released in 1980. Until I heard that song I believed the term was a disparaging comment aimed at someone with limited talents and abilities. This song made me think otherwise. Perhaps it is better to have one trick that you can do very well than to have a multitude of ordinary lackluster abilities.
What could this possibly have to do with golf?
