What’s better than television making fun of television? The Simpsons has arguably done it better than any other show, managing to deliver easy laughs in the form of terrific extended parody episodes like the two-part “Who Shot Mr. Burns?” in seasons six and seven, the brilliantly bizarre “The Springfield Files” in season eight, and even “24 Minutes” all the way in season 18. Viewers don’t have to watch Dallas, The X-Files, or 24 to enjoy those episodes either; the references simply work as structural guidelines and additional fun for people who do get them.
