Show: “The Simpsons” (Season 1, episode 1)
Airdate: Dec. 17, 1989
Overview: This is a classic not only because it’s a Christmas episode, but also because it’s the very first episode of “The Simpsons.” Sometimes when you go back and watch the first episode of a long-running series, it’s jarring how slow and boring it is. This episode is paced slowly but it’s not boring. We meet many major characters for the first time (although the Simpsons themselves were familiar to “Tracey Ullman Show” viewers), notably Santa’s Little Helper in the final act. When Homer brings home a free dog for Christmas, having failed to win any money at the dog track to buy presents, everyone is thrilled, and that wonderfully illustrates the spirit of Christmas.
