By poking around in our parent's internal state, we're tying ourselves tightly to its implementation. Say we decided to change Song to store the duration in milliseconds. Suddenly,KaraokeSong would start reporting ridiculous values. The idea of a karaoke version of ``My Way'' that lasts for 3750 minutes is just too frightening to consider.

When KaraokeSong#to_s is called, we'll have it call its parent's to_s method to get the song details. It will then append to this the lyric information and return the result. The trick here is the Ruby keyword ``super''. When you invoke super with no arguments, Ruby sends a message to the current object's parent, asking it to invoke a method of the same name as the current method, and passing it the parameters that were passed to the current method.
