Inside Larry & Sergey's Brain
In Richard L Brandt's biography of Larry Page and Sergey Brin there are at least two minor Muppet mentions. On page 3 he writes describing Larry Page "He rarely volunteers to answer questions unless specifically asked to address them. When he does, it's with a methodical intonation that sounds like a baritone version of Kermit the Frog". Then on page 53, while describing the formation of Page and Brin's company Google he writes "The first person they brought in, Craig Silverstein, is a computer geek in their own spiritual image. He looks the part. Short and slender, with a Stan Laurel chin and a usually shy demenour, in his spare time he runs an online fansite about Muppets."

Kissing Bill O'Reilly, Roasting Miss Piggy
"Hate - Roasting Miss Piggy" is featured on pages 205 to 206. The author prefaces his comments by stating that "Jim Henson is a genius, not a word I use lightly." He goes on to describe Frank Oz and his various Muppet performances. In regard to Miss Piggy, he states that she is the "... most popular Muppet and the least funny, most obnoxious yet bland, culturally influential of Henson's creations." He also laments her "trilled catchphrase" — Moi? — and comments that he would "like nothing more than to see her roasted on an invented garbage-can-top platter held aloft by Oscar the Grouch, a rotten apple stuffing her mouth into silence."
In chapter 12, the main character, Marcus, purchases "a T-shirt that had a Photoshop image of Grover and Elmo kicking the grown-ups Gordon and Susan off Sesame Street," as part of the growing "Don't Trust Anyone Over 25" popularity.
Never Can Say Goodbye
Subtitled Writers on Their Unshakable Love for New York, this 2014 book includes 27 essays from famous personages (mostly writers) about New York City. In "City of Mundane Fantasy", Elliott Kalan writes of his childhood affection for the mundanities of Manhattan life: commuting on the subway, working in an office, wearing a suit and tie. He relates that his first exposure to this was in The Muppets Take Manhattan, when Kermit the Frog was afflicted with amnesia and became mundane businessfrog Phil.
“Hidden among the movie's many scenes of dancing animal puppets was a truly inspiring vision of adult normalcy. Kermit, the Muppets' frog vaudeville ringmaster, comes down with a case of cab crash–induced amnesia and is handed the identity of Phil, a New Yorkad exec. Phil does not perform on Broadway or hang out with a bear. Phil wears a suit and works in an office. Phil's days are spent attending meetings and having diner lunches with his co-workers. I wanted to be Phil.
What to the filmmakers was clearly a fate worse than death, the stifling of a unique spirit by the square establishment, was to young Elliott a dream to strive for. The message of numb conformity totally failed to reach me. All I could see was that Kermit went from naked frog to independent adult, autonomous professional, self-supported citizen. That was the magic of New York. Even an amphibian could become a grown-up. I didn't want to marry a pig and put on a show. I wanted a subway commute and a greasy spoon lunch hour. I wanted meetings around wooden tables. I wanted a desk with a phone on it. The return of Kermit's memory was tragic. He lost all those amazing ordinary things New Yorkers get to do!”
The Order of the Stick

Playing with Power
On the front cover of Marsha Kinder's book, the title read "Playing with Power in Movies, Television, and Video Games: From Muppet Babies to Teenage Mutant Ninja Turtles" and in the book's official description, it read:
“Parents who worry that playing video games will turn their kids' brains to mush may welcome Kinder's view that the games contribute to a "ripening process . . . by fostering equilibration, by demanding shifting identifications with a wide range of subjects and objects, by forcing children to use the inductive process." This academic treatise swings between claims for the ostensible benefits of kiddies' TV shows, cartoons, videos and video games, and an analysis of how these same media instill an illusory sense of empowerment in children, serve as substitute parents and transmit consumerist ideology. The author, a professor at the University of Southern California School of Cinema-Television, psychoanalytically interprets the meanings of Muppet figures and applies semiotics to Garfield the Cat as one might hit a flea with a sledgehammer.”
