(Strip Number 7132, Original Publication Date, 13 February 1983)
Panel 1: We start things off with John greeting a Mr Hildebrant before he does some dental work on him.
Panel 2: Despite the presence of a dam on the man's mouth, he asks Hildebrant how the family is.
Panel 3: The strip most of Lynn's readers will see starts with John asking Gunther what he thinks of the current economic situation; the man's response is 'Mff, hmbrgl.'
Panel 4: His saying 'Mf, mf!!" probably means that he agrees with John's belief that they're probably in for a bit of a slump.
Panel 5: John's testy comment about how even the people running the country are just in it for themselves not only gets a question "Gmf?", it's also a bog-standard joke about political venality that allows John to think that he's wiser than he is.
Panel 6: John's asking the man if he can think of a single politician he could trust gets a firm response that makes as much sense as anything else I've heard: "BRGLMPH!!"
Panel 7: As he finishes up with Hildebrant, one of his assistants tells John that he's wanted in the next operatory.
Panel 8: Having looked over the man's file, John says that they're done with Hildebrant and thus can't understand why he wants to make another appointment.
Panel 9: Instead of being reminded that he has to come in every six months or so anyway, the woman tells John that Gunther wanted to talk.
Summary: The basic premise is a rather tedious and perfunctory joke that would occur to anyone married to a medical professional. The presence of a regular name instead of something like "Horgenstank", "Luggsworth" or "Gluttson" is explained in the notes by a long-winded comment about how Lynn and Rod wanted to say hello to a family friend.
