Krusty the Clown cited Armstrong's arrival on the Moon as one of the few significant events in television history.Armstrong had a booth at the Springfield Bi-Mon-Sci-Fi-Con, but no one wanted his autograph or even cared that he had actually been to the Moon. Annoyed by the convention attendees' indifference, Armstrong came close to firing his agent in a take on his famous "one small step ..." line ("This is one small step ... to firing your ass!").
In a flashback scene, Homer remembered the television coverage when Armstrong set foot on the Moon, and Armstrong's voice was heard as he delivered his famous "One small step ..." line. When Krusty was married to Holly Hippy, he prevented her from seeing the moon landing as he was jealous of Armstrong.
After learning that Maggie had her heart set on having the moon, Homer became determined to give it to her. Barney told Homer that he could buy the moon from him, because he won it from Neil Armstrong in a dice game. Homer then bought the moon from Barney for a beer and gave it to Maggie.
When Homer start killing celebrities so the advertising agencies can use them in commercials for free he kills Neil Armstrong. When Homer sat down on the carousel at Krustyland, he said that they are the first people "to ever ride this baby", and they are like "that space guy who did that moon thing!". Lisa asked if he meant Neil Armstrong. Homer replied that he meant Chewbacca.
