The Road Not Taken is the title of a 1915 poem by American poet Robert Frost. The same title has been used by a number of science fiction and fantasy productions.
It was at one point thought that this could possibly be the last appearance of Norm MacDonald on the show as he passed away in 2021, before Season 3 had been released. It was later confirmed that Macdonald completed voice work for season 3 before his passing and that Yaphit would have a recurring role. The season 3 pilot Electric Sheep (2022) is dedicated to Macdonald's memory.
Rare Star Wars reference: When LaMarr knocks on the door to the resistance bunker and Yaphit answers, it's a nod to a scene from Star Wars: Episode VI - Return of the Jedi (1983) where R2-D2 and C-3PO knock on the door to Jabba's Palace.
The show normally riffs on Star Trek, but in the parallel timeline the props, set design, and musical score are homages to its long-standing rival, Star Wars.
The masks that are worn in the beginning of the episode are from Captain America: The Winter Soldier (2014).
