Homer typing the same thing over and over spoofs the 1980 film "The Shining".
"Citizen Kane" is referenced multiple times throughout the episode, such as the "cane from Citizen Kane" and the scene where Homer tells Lisa, 'people will think what I tell them to think' and that she, 'can't do this to me, I'm Homer Simpson!' as she leaves the room.
In the scene where the restaurateurs, critics and animals are behind Homer and Lisa, and are about to give the former his comeuppance, Daphne Beaumont's lipstick disappears from her lips when she clenches her teeth.
Marge tells Homer that the E key on the typewriter is broken. Later, when he is writing a review of the Gilded Truffle on the typewriter, he types out several words with the letter E in them.
