"The Fabulous Faker Boy" is the twentieth episode of Season 24.
Marge encourages Bart to explore his creative side and take music lessons and Bart develops a crush on his beautiful piano teacher, Zhenya. To pay for Bart's music lessons, Marge agrees to be Slava's driving instructor. Homer is shocked when he loses the last two remaining hairs on his head and Patrick Stewart teaches Homer how to live with his newfound baldness. Justin Bieber tries to get into a talent show that Bart is playing piano and they won't admit him.
Marge is at Bart's school and in a conference with Principal Skinner, where they discuss about Bart's future. Skinner suggests that Bart should take music lessons.
While Homer is shaving his mustache, he finds what he believes to be a cork that is blocking the pipe, causing a lot of water to overflow in the sink. He realizes that, instead of a cork, his hair was blocking the pipe and frantically tries to put it back on his head. It fails and the hair goes back into the basin. He tries to stick them back on, without success. He resorts to wearing various hats and wigs to cover up his now-bald head.
Marge suggests that Bart takes music lessons from Lisa, Sideshow Mel, Comic Book Guy and Professor Frink, but chooses Zhenya, a Russian piano teacher whom Bart quickly develops a crush on. Bart later starts to perform better (with the help of a CD). Zhenya explains the actual reason for teaching piano: her father, Slava, wants to learn how to drive. Bart feels neglected soon after, and at a recital, he explains to Marge that he was faking piano playing the entire time.
Marge is displeased at Bart until she learns that Slava obtained his driver's license by bribing Patty and Selma (although it was a bigger reaction when he tells her that Russian dressing is just thousand island). Slava convinces Marge to forgive Bart, and she does.
Later that night, Homer explains to Marge that he lost his last two hairs. She comforts him, and his hairs grow back.
Even though fans liked the "Robot Chicken" couch gag, this episode received mixed, but mainly negative reviews from fans and critics.
Robert David Sullivan of The A.V. Club gave the episode a C–, saying that "the relationship between Marge and Bart is actually one that hasn’t been done to death on The Simpsons, but it comes up too half-heartedly and is resolved too quickly in this episode."
Teresa Lopez of TV Fanatic gave the episode two and a half stars out of five, saying that "Not only was the mother-son dynamic shoved into the narrative late in the game, but Marge's disappointment was easily waived away by her Russian driving student saying Bart cheated for love and for his mother. Kind of a simple rationalization, right? The B-plot involving Homer's loss of his last two hairs did lead to some hilarious The Simpsons quotes and an amazing guest appearance by Patrick Stewart (I could see your belly), but it was mostly a distracting vehicle that allowed Homer to try on various hats."
