The passage describes taking a 5-year-old son, Willy, to a musical instrument store to buy him a junior drum set. On the way, they see a policeman regulating traffic and blowing his whistle. Willy unexpectedly asks why the policeman is using a whistle and not a drum. His father answers jokingly that it is "because he is not Phil Collins." The humorous twist in the story is Willy's unexpected question about the policeman's choice of instrument.
