Trivia: When Topanga says "I will only answer to the name," and then proceeds to growl, after the laugh track dissipates, you can hear members of the production crew laughing. Apparently this scene was not filmed in front of an audience due to the amount of chaos being filmed, which is why the laughter of the crew is audible. (00:13:30)
Trivia: According to the Pod Meets World podcast, the ethnic slur that Linda is called was originally in the episode's script. Ben Savage had never heard the word before and mispronounced it at the table read. The slur was ultimately removed from the script, likely at the request of the studio, though the different ethnic slur directed towards Shawn strangely made into the episode. Cory later mispronounces "antisemitism" later in the episode, and Will Friedle pondered that Ben's mispronounciation of the Asian slur at the table read was the reason for that.
Chosen answer: In the present day, with the United States abiding by more stricter school health laws, for the most part this wouldn't be in school cafeterias as many cannot even have carbonated beverage machines now. However, in the 90s when the show takes place, it wasn't unheard of for there to be coffee machines in the cafeteria of small schools where the teachers eat with the students as we see them do often in the show. The idea being that the cafeteria was small enough so a teacher or hall monitor could catch a student before they could drink the coffee.
