“Simpsons, eh? Never heard of it.” Well, Mr. Burns might say that, but any comedy and/or animation fan who has owned a TV in the past three decades knows about The Simpsons, and Fox and FXX are marking the toon’s 30th anniversary with a pair of special events this month.

Fox

The FX Networks cable net has scheduled a butt-numbing 15-hour Simpsons marathon on December 16, with 30 episodes handpicked by longtime exec producer Al Jean. Featuring one episode from each season, it kicks off at 9 a.m. and runs through midnight.

Over on the broadcast network, the Christmas-themed first full episode in the adventures of Homer, Marge, Bart, Lisa, Maggie and myriad Springfieldians will air at 8 p.m. “Simpsons Roasting on an Open Fire” features Homer (Dan Castellaneta) trying to earn extra money to buy Christmas presents for the family, but everything he does goes wrong. Fortunately, he is rescued by Santa’s Little Helper.

After debuting as a series of shorts on then-nascent Fox’s The Tracey Ullman Show, that first full episode of The Simpsons aired December 17, 1989. Its Season 30 premiere in September was its “Ay Caramba!”-worthy 640th episode.
