* HarsherInHindsight: In one episode, Lamb Chop tries to convince Shari that she has pneumonia so that she'll stay home with her (Shari is unconvinced). Shari Lewis would die of pneumonia on August 2, 1998, while undergoing treatment for uterine cancer.
* HilariousInHindsight: In one episode from 1994, Shari reads the story of ''Literature/TheElvesAndTheCobbler'', and Charlie Horse mistakes the word "elves" for [[Music/ElvisPresley "Elvis."]] In ''Film/MuppetClassicTheater'', which was released later the same year, Rizzo the Rat makes the same mistake, which leads to a version of the story where the elves really are Elvis lookalikes.
* JerkassWoobie: Charlie Horse in the episode "So Long Freddie" when he has to deal with his titular friend moving away.
* ViewerGenderConfusion: Due to her lack of TertiarySexualCharacteristics (other than her exaggerated eyelashes) and her feisty personality, some viewers have mistaken Lamb Chop for a boy. This might explain why in ''Series/CharlieHorseMusicPizza'' she started wearing girly pink or lavender outfits more often.
