The Cowboys named me Jester.  It was a good name.  I earned it.  Then the Peloran named me Hart.  It took a while for us to make the change.  We felt they were trying to take our real names.  In time, we realized that the names fit us, often better than the names we were born with.  I stopped using my old name altogether.  It became the past, the person I was before The War.  I am Cowboy Five, and I will be until the day I die.  My name is Jack Hart.
