The Simpsons

The Simpsons is an American animated sitcom created by Matt Groening for the Fox Broadcasting Company. The series is a satirical parody of a middle class American lifestyle epitomized by its family of the same name, which consists of Homer, Marge, Bart, Lisa and Maggie. The show is set in the fictional town of Springfield and parodies American culture, society, television and many aspects of the human condition.

"Treehouse of Horror XII"
In the third act "Wiz Kids", Lisa and Bart attend Springwart's School of Magickry. Harry Potter is in their class and they must fight against the evil Lord Montymort (Montgomery Burns). Harry has only one line: "No, ma'am, it's brimstone", spoken after being accused of chewing gum.

"The Haw-Hawed Couple"
Lisa asks Homer to read her Angelica Button book to her for bedtime. Homer, learning that the character Headmaster Greystash will die (à la Albus Dumbledore in Harry Potter and the Half-Blood Prince), hides the fact from Lisa by inventing a happier ending, though Lisa does read the real ending and decides that Homer's was better.

"Smoke on the Daughter"
The Simpsons go to the midnight release of the final Angelica Button book. On the ride home from the store, Lisa skims through the book, revealing all of the best parts. Once Lisa reveals that the book ends well the Simpsons exclaim "Yay!" and all except Lisa throw their copies of the book out the car windows.

"The Regina Monologues"
J. K. Rowling made a guest appearance as herself in the special British-themed episode. The dialogue consisted of a short conversation between Rowling and Lisa Simpson, who mispronounces Rowling's name. She acknowlewdges Lisa with "Thank you, young Muggle". When Lisa asks her about the ending of Harry Potter, Rowling sighs and says: "He grows up, and marries you. Is that what you want to hear?" to which Lisa swoons and dreamily replies, "Yes!" before Rowling rolls her eyes and walks away.

The Simpsons Movie
Harry Potter is mentioned briefly as 'Harry Plopper' in the form of a pig that Homer had rescued from Krusty Burger.
