These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: What's Happening!!
Acceptable Targets: Rerun and Shirley are mocked—and they insult each other—because of their weight. Mrs. Thomas is also obese, but nothing much is said about her weight.
Fear of Mrs. Thomas is probably what prevented that; would you make fun of her weight?
Jump the Shark: When the three friends went to college and two characters, Big Earl and Little Earl, were introduced many fans claim the show lost its original charm.
Tearjerker: The episode where Dee, Yes THAT Dee, befriends a rather gruff old man while her brother is in the hospital. Her reaction to his death, in addition to being a Tearjerker, is also a Crowning Moment of Heartwarming . Dee tells the man's daughter that he'll be all right because you can't get hurt sliding into a cloud.
