Crocodile Tears: Weaponised by Bart and Lisa to skip the line for a waterside. Lisa starts crying and screaming "I want my mommy!" while Bart acts like the concerned big brother, pushing past everyone with Lisa close behind.
Diet Episode: The first of many involving Homer. Played more realistically than most in that Homer's weight loss isn't dramatic or significant enough to alter his appearance much, he simply loses enough to reach a healthier weight (and because he was humiliated on the news).
Jerk with a Heart of Jerk: Marge discovers that Mr Burns has absolutely no redeeming qualities, making it difficult for her to make a good painting of him. She tries to tell him she can't paint a positive picture of him due to his behavior, but Mr. Burns cuts her off by saying he needs the painting done on time and tells her to shut up and paint.
Kent Brockman News: The news anchors cracking jokes about Homer's weight while on the air.
Kick the Dog: Burns making fun of Homer's attempt at losing weight, driving Homer to binge on food again until Marge stops him. It is also the final straw to Marge realizing Burns has no redeeming qualities and pretty much tells him to get out.
No Name Given: Subverted. Apu's first name is revealed in this episode.
Scenery Censor: Marge runs into Mr. Burns getting out of the shower, his private parts covered up by her arm. Later, when Marge's portrait of Burns is unveiled and it turns out to be nude, the crotch keeps being blocked by people's heads or hands.
