The title of the episode refers to an earlier Simpsons episode: "Bart Gets an "F"". This title would be later reused for other episodes such as "Bart Gets a "Z""
When Santa's Little Helper is chewing on the remote changing the channels, Kent Brockman is shown talking about a woman hunt is out with a picture of Lucille Botzcowski, showing that she is still on the run after "Some Enchanted Evening".
Another clip during Santa's Little Helper's channel-surfing shows Troy McClure hosting "I Can't Believe They Invented It!" but without Phil Hartman's voice.
Lisa wears her teal nightgown instead of her usual red dress throughout the episode (due to staying home from school because of the mumps) and (if you listen closely) her voice is a little bit different when she has the mumps.
When Marge and Lisa touch their fingers together, it is a reference to E.T. the Extra-Terrestrial, and the theme to the movie plays in the background as well.
