Main

 * Oh, the Places You'll D'oh is a parody of the Dr. Seuss book, The Cat in the Hat, and the title is a parody of another Dr. Seuss book, Oh, the Places You'll Go, the last book that he made.
 * The mask The Fat in the Hat wears when blowing up city hall looks similar to Guy Fawkes Mask from the movie V for Vendetta.
 * At the end of the segment, The Fat in the Hat says not to let him be played by Mike Myers, a reference to the fact that Mike had played the title character in the  live-action adaptation of The Cat in the Hat.
 * Dead and Shoulders is a parody of the film, The Thing with Two Heads, and the title is a parody of the shampoo brand, Head &amp; Shoulders.
 * Freaks, No Geeks is a parody of the film, Freaks, and the title is a parody of the short lived show, Freaks and Geeks.
 * The last scene where Homer says "And that, kids, is how I met your mother" references the show, How I Met Your Mother, and its theme music plays over the credits.
 * When Krusty is the funny man he says "Seriously folks, I really think we shoud stop this Hitler guy " and everyone laughs.

Trivia

 * This is the first THOH episode since X to have a couch gag.
 * This is the second episode to have a person's head stitched onto another person's shoulders; Mr. Burns' head was attached to Homer's body in an earlier THOH.
 * Marge's face is never seen in the first segment (Oh, The Places You'll D'oh!).
 * Nelson Muntz is seen as a donkey boy which is a possible reference to Disney's Pinocchio.
 * Skinner appears as a freak called the Spineless man. He appeared spineless in "Treehouse of Horror XIV". The title also pokes fun at his character.
 * The Gracie Films logo didn't have the scream and instead was replaced by people shouting 'one of us'.
 * This is the second Treehouse of Horror opening to be based off the normal opening, following Treehouse of horror IX.

Goofs

 * Freaks, No Geeks was supposed to take place in 1932 but when Homer tells the kids his story it's in the present time. Since this is non canon, he could have lived for 81 years after the incident but it says in the last article that he died. He must've faked his death at the time.
