Plot.
Bart, Milhouse and Homer line up at Comic Book Guy's store to purchase the first issue of a Radioactive Man reboot comic. Comic Book Guy finds out that his competitor Milo (the owner of Coolsville) is now married to his girlfriend, Strawberry. Comic Book Guy cries and sings a song about him being lonely his entire life. Suddenly, an imaginary Stan Lee appears to Comic Book Guy and tells him that he has another chance in love. A Japanese girl named Kumiko Nakamura enters the store, and Stan Lee advises Comic Book Guy not to waste the opportunity. Kumiko is in the US to do research about the country's saddest cities for her autobiographical manga. Comic Book Guy asks her out for a date, and then asks Homer for dating advice, since Homer is the only fat man in real life who is married to an attractive woman. During the date, Marge advises Comic Book Guy to not be himself, but Kumiko actually likes Comic Book Guy's real personality.
Comic Book Guy continues to date Kumiko, and they both decide to move in together. While dropping off a gift for Kumiko and Comic Book Guy, Homer meets Kumiko's father in front of the store. Homer tells him about Comic Book Guy being an obese nerd, which prompts Mr. Nakamura to object to their relationship and take Kumiko away. Marge tells Homer to fix things up, so Homer takes Mr. Nakamura to a Japanese bar. They both drink Habushu (Snake Rice Wine), an incredibly strong form of rice wine (and Homer drinks what he thinks was fish wine when actually it was the restaurant aquarium) and stumble home intoxicated, where the city turns into a wonderland based on Studio Ghibli's films (specifically "Spirited Away", "My Neighbor Totoro", "Ponyo", "Princess Mononoke", "Howl's Moving Castle", "Kiki's Delivery Service", and "Porco Rosso"). Mr. Nakamura learns that by forbidding the relationship, he is taking away Kumiko's life.
Comic Book Guy tries to impress Mr. Nakamura by getting a real job using his hitherto unmentioned chemical engineering degree. Mr. Nakamura tells him that he does not have to get a real job since he already likes Comic Book Guy the way he is. The episode ends with Comic Book Guy and Kumiko getting married by Stan Lee in Comic Book Guy's store.
Reception.
The episode received generally positive reviews from critics. 
Dennis Perkins of "The A.V. Club" gave the episode a B–, saying "I don’t want to be too hard on this episode. It’s always promising when the show tries something new, even if the results ultimately prove that not all experiments work out. And while I can’t say I’m clamoring for Comic Book Guy to enter "The Simpsons"’ regular rotation, the ending was a touching example of catchphrase re-purposing." 
Tony Sokol of "Den of Geek" gave the episode a 3.5 out of 5, signaling moderate reviews, saying "if you want to know if this is a good episode, I’d answer with an emphatic: kinda. A lot of "Simpsons" episodes that focus on secondary characters aren’t as crisp as the one focusing on the family, but ‘Married to the Blob’ only suffers because it is in the middle of a particularly good season."
Teresa Lopez of "TV Fanatic" gave the episode a 3 out of 5, saying "Best episode ever? Not really, but I quite enjoyed all the comic, sci-fi, and various pop culture references." She then commented positively on the guests on the episode, saying "with appearances from Stan Lee and Harlan Ellison and a romance blossoming across the pages of Kumiko's Manga comic, the story was sweetly and entertainingly told. Kumiko's admiration of Comic Book Guy's snark perfectly reflects the reason why most "Simpsons" fans love Comic Book Guy. Plus, the hallucinatory sequence was a beautifully animated tribute to Anime director Hayao Miyazaki." 
Christian Allaire of The "National Post" also noted the hallucination scene, calling it "a charming tribute to animator Hayao Miyazaki."
The episode received a 2.2 rating and was watched by a total of 4.83 million people, making it the second most watched show on Animation Domination.
