Bart is watching Itchy & Scratchy on TV, the sound of theme song can be heard from the TV when Lisa talks to Bart, we don't see it in The Itchy & Scratchy episode but the sound from cartoon is clearly.
The car Bart rents resembles a Mercury Grand Marquis.
The radio in Bart's car is tuned on 94.5 FM, and the song that played before Milhouse plays with the radio dial is "Radar Love" by the Dutch rock band Golden Earring.

At the end of the episode, Marge gets a call from the Tennessee State Police. However, in real life, the department is called the Tennessee Highway Patrol.
This episode has slightly foreshadowed another Spring Break episode, "Kill the Alligator and Run," because Bart briefly had his friends vote for either Disney World or Knoxville. Disney World is a resort in Florida, the destination of the latter episode.

Bart's first action with his fake ID was taking Nelson, Milhouse, and himself to see the film adaptation of Naked Lunch. In addition, after seeing the movie, Nelson says "I can think of at least two things wrong with that title...", alluding to the film being a very loose adaptation of the book of the same name.

When Milhouse opens the glove compartment in the car to reveal a guidebook, the lines on the side of the book representing pages disappear, making the side simply look smooth white.
When Lisa and Homer are spinning on the chairs, you can hear Homer laughing, even though his mouth does not move.
Also when Lisa bumps him by her chair it makes Homer turn on his chair but in a close-up look at him he is turning in opposite direction.
