It could also be taking a jab at the internet-famous Creepypasta, "Dead Bart", which was presented as a lost episode from the first season of The Simpsons, featuring the death of Bart Simpson. However, "Dead Bart" is a fan-made episode, as it is not official, since it uses the image of Homer’s melted face from “Brother from the Same Planet” and various shorts.
Also as in previous episode Bart was hit by a thunder this title could indicate that Bart didn't die due to that. So this episode could be a sequel.
It may also have been titled to play off of the season premier of South Park which aired 4 days earlier. It revolved around school shootings and was titled "Dead Boys".
Homer tells Marge at the hospital, "as someone who has fallen off of cliffs lots of times". This could be referencing "Bart The Daredevil".
In the opening to this episode, it reuses scenes from the past 29 seasons.
The second set of credits at the end of act 3 has only one S in the last word of "Springfield Film Commision".
