episode ends with "Little Bird, Little Bird", an American children's song, performed by Elizabeth Mitchell. The cultural references in the episode include when Hermes and Bender enter "cubicle room 729", with cubicles set up in groups of nine, three rows across and three columns down. In order to get to Hermes' cubicle, the group rotates right and left and up and down in the same fashion as a Rubik's Cube. When Hermes's cubicle stops, he says, "This is mine, right next to the center square," also referencing the game show Hollywood Squares. The bureaucrat next to Hermes makes a comment and a red 'X' pops up on his desk. This is a reference to actor and comedian Paul Lynde, who was the regular "center square" on the show. The episode deals with the concept of realizing one's mortality and discovering that life is more precious because of it.

He deals with the devastating news of his newfound mortality by trying to find the one person who he believes can answer his questions about the reason for his life and why he was allowed to "be born" only to die. Though Bender cannot find the answers to his mortality, he ultimately ends up developing a new outlook on life, believing it to be more precious than it was before now that it is finite, and he resolves that life is worth living no matter how brief it is.
