(Strip Number 4940, Original Publication Date, 7 March 1988)
Panel 1: We start things off with Mike walking up to John as he listens to old people music from a dead man whose name he probably still pronounces Chop-Inn.
Panel 2: Since he thinks that old people music is why his folks act like old people who don't enjoy life anymore, Mike helpfully replaces John's headphones with his own and says "Here, Dad!"
Panel 3: John reacts to his exposure to loud rock music by looking as if someone large had grabbed onto him and shaken him violently.
Panel 4: Since Mike is not yet aware of the ground rules of the universe he lives in, he can tell John that he wanted him to listen to something good for a change and still think that he's a goofy kid with different tastes in music (which is what he is to me) and not what he's meant to be by Lynn: an evil monster spreading chaos.
Summary: We revisit this theme later when Mike tells Elly that the only reason she feels old is that she acts old, eats old people food and listens to old people music only for her to think that exposure to Flavor Flav will kill her dead.
