The title screen gag of this episode is a reference to the English folktale Jack and the Beanstalk, with Bart cast in the role of Jack. Bart is shown carrying a harp and a goose down a beanstalk; in the folktale, a magical harp and a goose that lays golden eggs are among the items that Jack steals from the giant.
A red can of paint thinner is seen again (though not identical), which was last seen in "Homer Scissorhands."
Bart creates a graffiti image of Skinner saying "I am a wiener," just like he did in "Bart the Genius" (and did again in "Principal Charming," with the graffiti image: "I am still a wiener"). This time, however, the word "wiener" is spelt with an "ie," not an "ei."
Bart's graffiti artwork is also central to the plot in the comic story Picture Perfect.
The last episode to feature a montage where a modern work of art is spread to the public with a classical music piece playing was "Homer The Whopper".
The song played in the credits is an "A cappella" cover of the theme song, made by the YouTube user mmckaig.
Surprisingly, everyone has moved back to Springfield after the previous episode, At Long Last Leave, aired.
The phone wire wasn't shown until Homer checked it.
The first part of the episode is set on March 18, as shown by the calendar held up by Lisa at the beginning of the episode. However, a flyer for I, Carumba: The Nightmare World of El Barto states that the dates of the art gallery show are March 11 - August 15, a week before the start of the episode. Bearing in mind, Bart chose to become a graffiti artist after Marge's birthday on the 19th and approximately two days passed between Bart becoming a graffiti artist and Shepard Fairey persuading Bart to open the art gallery.
Bart is seen using his right hand whilst spraying graffiti, but he is left handed.
