The comic book that the chimpanzee is leafing through at the end of the story is "Pluto", named after and about the Walt Disney cartoon character. Specifically it is Four Color #1248, Walt Disney's Pluto Joins The Circus, cover dated November 1961.
This is one of several Ozzie & Harriet radio and TV episodes featuring a character named Fifi La Plume. In this case the character is an ostrich, but previous incarnations have been human. They are not the same character, just a name that kept getting reused on occasion for more than a decade throughout the series.
