“Sir Jasper Finch-Farrowmere?” said Wilfred.“ffinch-ffarrowmere,” corrected the visitor, his sensitive ear detecting the capital letters.

The joke turns on Wodehouse’s fondness for social satire and linguistic play. A name like “Jasper Finch-Farrowmere” signals inflated gentility, and the visitor’s correction—pronouncing it as if the capitals were audible—parodies the obsessive self-importance of people who treat rank, hyphens, and pedigree as matters of acute sensitivity. The humor comes from treating typography as sound: the “sensitive ear” that can “detect” capital letters is an absurd literalization of snobbery. In miniature, the line skewers class pretension and the performative policing of status markers, a recurring Wodehouse theme.
