(Strip Number 4610, Original Publication Date, 21 April 1986)
Panel 1: We start off with John telling a Mrs Weiss to put on a headset because it'll be easier for her to relax if she listens to music.
Panel 2: He then tells Elly to look in the storage room for the cassettes.
Panel 3: For some reason, Mrs Weiss is tapping her hands and imitating the sounds of some sort of musical instrument thereby making it hard for John to get her dental work done for her.
Panel 4: Elly explains that the only cassette she could find was "Polka Hits Of The Fifties."
Summary: If we get notes, we're either going to be told how much Lynn loved I Love Lucy or we'll have to absorb the same sort of snotty comment about piped-in music that she's going to make in about a year or so when she thinks Muzak is going to turn a dental clinic into a dance hall.
