The marathon every-episode showing of The Simpsons has been going nonstop for six days now, and we’re not even at the halfway point. Amazing. So tune in any time for more fun – though, of today’s batch, I have a particular fondness for “Trilogy of Error,” televised tonight at 10:30 ET. Why? Partly because its structure is particularly complex and inventive, and partly because the title is a play on an excellent Seventies-vintage TV movie, Trilogy of Terror, starring Karen Black, and partly because Homer loses part of his thumb in an accident, which is clumsy even for Homer. All of which compels me to give the episode a non-severed thumbs up.
