Uncle $crooge sends this in: “It’s probably some kind of weird McEldowney fetish so I probably will regret sending this in and learning something that I really don’t want to know. Still, maybe it’s just a harmless joke; I just have no idea what this strip is about.”

I don’t really understand it, either, but I’m giving it an Arlo tag just because it’s McEldowney. The ones before and after this one are also themed The Thorax Clinic, but have a different patient.
