This is the first (and the only) episode so far that Bart doesn't appear in (not counting the opening sequence but including the LEGO Bart in Brick Like Me). However, he is seen in a picture in Marge's room.
This is one of the episodes in the show's history where Maggie has spoken and the second where she has done so directly.
Selma appears without Patty in the Queen Elizabeth segment.
This episode was viewed by 5.15 million viewers, making it the least watched episode in the history of the show. Almost a year later, it was beaten by Million Dollar Maybe.
The music playing during Maggie's story is the Second Movement of Beethoven's ninth Symphony.
The picture that Maggie draws on the wall in the final scene is Vincent van Gogh's "Starry Night".
In the Fountainhead parody, Ellsworth Toohey (a character from the book and movie) appears as himself, with no attempt to caricature him as a regular Simpsons character.
The episode's title is a parody of Three Men and a Baby.
Differences from Snow White and The Seven Dwarfs
It is very likely the way the story was told it was parodied after Disney's Snow White. However Lisa said it was from the fairy tale. Here are the differences.
In the movie Doc is the leader of the Dwarfs. However in this version Doctor Hibbert is in back and Crabby/Moe is the leader.
In the movie and original, the object that tells the Queen who is the most beautiful is a mirror. But this object is an HD-TV.
One of the biggest differences is Snow White's appearance. In the movie she is 14 and by birth a princess. She has black hair and is wearing a yellow and blue dress. But this version has her as a peasant and not related to the Queen. She is also about 12 and is very different from the movie.
In the movie and original, the person hired to get Snow White's heart gives the heart of a pig. But in this version the Queen wants her heart in one box and her body in another. Also, she is not given the heart of anything. It is unknown what became of Huntsman Willie.
Marge complained that Homer killed everyone in their costumes, however Doctor Hibbert was not.
